My theory is he just sent them a new pair to keep the pressure off of himself in the rebuild turnaround time. Makes for happy customers, too, I'd think! 
There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakersare used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Good call guys, with him knowing back surgery was coming up thats probably what he did.
So his customers wouldn't be without their equipment for an extended length of time.
He said  he was going to need 6 mo. to recover from this latest surgery.

Sold by Bob today, November 6, 2015 on eBay was a pair of 350 tube amps for $6100. Tung-Sol KT-120 output tubes. Pretty much the same information posted in this auction as in all the others but here's the Q&A for posterity. Read from the bottom up.
 
Question & AnswerAnswered On
Q: Hi Bob, Was this a 'tongue in cheek ' explanation, or did I miss something? I am a great fan of so many of the products that you created. I can't find the words to describe the warmth and delight that I feel when you respond to questions on EBay with such candid, humble and intelligent answers. Here is the sentences that I initially referred to. Since there are two output transformers, one for each amp, it takes me four days to build a pair. And because I have a day job, I've been building them on weekends and in the evenings. Bob: What does your day job consist of besides being a genius (in my opinion) and running your Company? Respectfully, JeffreyNov-04-15
A: Hi Jeffrey, I was simply explaining why it took me so long to build a pie-wound output transformer. My biggest problem, believe it or not, was getting all the windings correctly hooked together after they were on the bobbin. So many wires! For the life of me, I kept making simple errors in phasing and sequencing when it came time to connect them all! I could hardly believe how difficult it was to solder all those wires without making a single mistake. I finally resorted to a simple and effective labeling scheme developed by David Hafler at Dynaco. My "day job" was my full-time CEO job at Sunfire. I hope I explained it better this time! Thanks for writing. Warmest and best, Bob Carver
Q: Hello Mr Carver, I m a huge fan and I am lucky enough to have one of your grand cinema Signature Series as my first amplifier for a home theater system which is still going strong. My question is about the amplifiers you have for sale here, is it a pair of amplifiers you are selling or just one single amplifier? Thank you for your time and your passion for high quality products. Im so thankful for the one i have. Sincerly David HorsleyNov-03-15
A: Hi '125, Good catch, I should have been a bit more clear in my description; the auction is for a pair of amplifiers. Still, it takes two for stereo, and you will receive two mono units if you win my auction. Good luck and happy bidding! Warmest and best, Bob Carver
Q: Hi, I want to clarify if this is the Vacuum Tube Cherry 305 watts first generation or the latest Crimson 350 watts; If this is the Crimson 350 how do I know?Nov-01-15
A: Hi 'love, This is the latest crimson 350. I should have been clearer, I know. There it is though, the Crimson 350 watt per channel mono-block amp, for a total of seven hundred watts! Warmest and best, Bob Carver
Q: Greetings! I have owned a pair of your root beer 180s for years...never had to replace a single tube and they drive my apogee speakers with aplomb! These amps are capable of floating an enormous and very detailed stereo image between and around my speakers which conveys a sense of depth that is not possible with other tube amps. Q1: There were only a few root beer brown mono 180s made by you and put on ebay (I am guessing about 6) because you ran out of transformers...remember...you know the military-grade transformers you carried around in the trunk of your car for years when you went to college..Well I am curious...what kind of trannys are they and how many did you install in 'root beer monos' before you ran out? Q2: How can I get another signature on my 180 amps...when I waxed them with a top grade of carnauba wax it completely dissolved your and Tom's gold penned signature & greeting on the top of the tranny covers! Now they are blank! Best wishes and keep those great amps comin'Nov-01-15
A: Oh Wow! What a beautiful letter; you have definitely made my day! Thank you. I don't remember how many exactly, but as for how I wind them now, they are multi-layer wound, with many, many layers in order to achieve the response I want. I like a great high frequency response because that allows modest feedback and really good sound. Really good, and that is an understatement! Thanks for writing, Bob Carver
Q: Hi Bob, Jay Fletcher from Oklahoma, good to see you are still building and selling those GREAT mono blocks, dearly love and still enjoying mine... Looking at the picture of the underside of your amps I see seven 470uF caps, I might be wrong but didn't the earlier ones have six? have you done some improving or modding the power supply section if yes should I have mine done? I remain a fan of Bob Carver..."jay"Oct-30-15
A: Hi Jay, Good to hear from you, good catch, and a great question too. When I increased the power to 350 watts, I increased the energy storage by the same amount because power is energy divided by time. The pictures are actually "file" photos, taken when the amp was a lower power unit. I wanted to take some new pictures, but I became lazy and procrastinated too long (one of my many character flaws). So I used some older pictures. The new amps look better than the pictures show. New color; the amps have a removable line cord, balanced inputs along with the standard RCA inputs, and the amps have the back panel well labeled as well. And no, your power supply is just fine, it supplies all the current needed into any rational load. The only reason for increasing it would be if the power were increased, but that means a completely new design with a different power supply, a different output transformer as well as a myriad of additional changes. The sound itself would not change at all, only the output power; the sound would be better when high output power is required because amplifier "clipping" would be virtually completely avoided. Great question, Warmest, Bob Carver
Q: I just realized that it wasn t clear if we are bidding on a pair or a single ampOct-28-15
A: Hi 'dwar, Good catch. It's a pair you are bidding on. Sorry about that. You get both channels for the price. . . Hope this helped, Bob Carver
Q: These monos are better in quality to ear 529??? The ear 529 are close to quad II in character but incredible high and bass and more neutral.The ear 529 seem small triode amps. The Carver's monos have this character?The power is controlled??Oct-28-15
A: Hi '1972, My mono amps cost a lot less than the $27,000.00 dollars a 529 costs. The 529 was designed by Tim long ago and was at the time his penultimate design and it was STUNNING! Now, moving up in time we come to the present, and find that both Tim and I actually had a large contribution to my amps here. Tim's teachings have changed over the years as he has evolved into one of the greatest amplifier designers in the world. His latest designs are far more like the amps here than the 529s were so long ago. Do these Carver amps sound better? YES they do. More humbly, yes I think they do. Here is why: They incorporate Tim's latest thinking and my latest thinking (regarding tube amplifier design). These amps represent my best work, I have poured more of myself and time into their design than any other. Hope this helps. Best wishes and warmest regards, Bob Carver
Q: Hi Bob, Really glad to see you're still building. I want to first tell you that I my most cherished component is a Carver SD/A 490t CD player with the tube buffer (I think it's a buffer) or output stage, and I have two of them. It was the 'tweak' that my wife heard immediately, and you know what that means. I play one directly into a rebuilt classic Dynaco ST 70 to drive a pair of ten inch Tannoy concentric from the late seventies; no preamp, and the other through an all factory original ST 70 (rivets instead of screws) where I play different speakers. Ok, now the question, I've never seen any mods for the ST 70 that use the DC Restorer and wondered if you've ever considered designing a DC restorer circuit to modify an ST 70? Oct-28-15
A: Hi '012, You are making my day. Honest. What a beautiful vintage system you have - sure brings back memories. I'm a bit jealous! I have not ever installed a restorer in an ST 70, but it would be easy to do. Actually a walk in the park! If toy want to try it yourself, I'll design one and send it to you. Send me your address: bob dot sunfire at gee male dot come. That's code of course. Best wishes, Bob Carver
Q: I want to participate in the auction item you paid when an elevator car and brass thanksOct-27-15
A: Hi '2014, come on and join the auction! you don't need to wait for anything. Thanks Man. Warmest and best, Bob Carver

After a year long hiatus Bob returned with another set of 350's, this time going for $7401US.  Once again here's the latest Q&A to br read from bottom to top for proper chronology. No real new info is given but herein preserved for posterity.
 
 
 
Question & AnswerAnswered On
Q: I am curious about your mention of the speakers "listening" to the room. I have heard of this about tube amps being able to improve the realism of the sound when they take advantage of this phenomenon, but I am not sure I understand who it works. My impression is that when sound is reflected by the walls and then reaches the speakers, the speakers are move slightly by these reflections. This movement of the speaker voice coil creates a small current, which returns via the speaker wires to the amplifier, which incorporates that tiny signal into the much larger signal being sent to the speaker, ultimately improving the sense of depth and space, improving the sound relative to the room and position of the speakers. Am I close?Nov-04-16
A: Hi hundred' I must say, not only are you close, you are right on the mark! Strange as it seems, the reflected energy, instead of being bad for the sound (as many reflections often are), actually substantially improves our sense of three-dimensionality by allowing the spatial information contained in those record grooves to be heard in a very beautiful, believable, and satisfying way that otherwise would not be possible. Great question, extremely complex, but you made it easy for me to answer! For that, I thank you sir, and I do so from the bottom of my heart. Thanks for writing in, Bob Carver
Q: This auction ends exactly 1 year from the last 350's you sold here. I wonder if this was intentional. At any rate, I just wanted to attest for any would-be bidders that what they're bidding on is in fact a marvelous pair of amps they would be glad to own for many years. I should know, I have the Carverfest Rootbeer 180's from 2008 and will keep them until death do us part. In fact they may have to be a special line item in my will. Bob, this is just my small way of saying 'thanks' once again. For all other readers, Bob's amps are simply the best!Nov-02-16
A: Hi 'rama, Good to hear from you again, and yes, the timing is pure coincidence. You have truly made my day, I'm ecstatic that your amps are sill playing great music after all these years. I owe YOU a huge thanks for being my customer and for enjoying my creation. Best wishes and warmest regards, I really mean it. Honest! Bob Carver
Q: Hi Bob, I'm sorry to bug you, but I've been waiting for you to list something. What was the base chassis of the little amp that had the awesome transformers you built last year I think? It was like a 10 or 20 WPC amp. Thanks! TristanOct-31-16
A: Hi Tristan, that would have been a small Packard Bell amp taken out of a vintage console built during the 1950's Great transformers! You can contact me bob dot sunfire at gee male dot come Great question, Bob Carver
Q: Bob Can you recommend a preamplifier that would match these amps? I have a Sunfire Amp. Big Fan of yours.Oct-31-16
A: Hello '1970, My favorites are a Carver or Sunfire tube preamp, or the world famous Citation 1. It was the Citation 1 that started me on my professional path so many long years ago. Thanks for being my fan, I'm yours too. Bob Carver
Q: Not a question , just dropped by to say hello from Jay and Melissa in Oklahoma... Good to see you and Tubular are still Joe still making those GREAT amps... Still got mine, been 6 years sometime this year... Did you go to Bob Carver Fest this past Sept? Best Regards, JayOct-31-16
A: Oh Man! A blast from the past! It's nice to know your amp is still working after all theses years - someone famous once said that;I don't remember who though. And yes, I did go to Carverfest and had a ball. We, Peggy and I, stayed the whole time and had lots of fun walking from cabin to cabin and listening to all sorts of systems, but mostly we enjoyed the amazing camaraderie, super audiophiles all! Warmest, Bob Carver
Q: If you ever want to talk to one of your greatest followers give me a call...I would love to talk to a true audio legend...mind you I am just an ordinary man...no technical ability whatsoever On 10/29/16, 22:47, audioshopper wrote: Re: roughcut48 has sent a question about item #192011232255, ending on Nov-06-16 16:28:53 PST - Carver 350 Watt Stereo Monoblock Tube Amp Amplifier Hi Bill, Do I ever understand about back troubles; I fell off of a roof two stories high and landed in a sitting position on the concrete - lower spine has a big ouch now.

If you would like your solid state amp to sound a bit sweeter, install a 1.5 ohm, twenty-watt resistor in line with the hot wire from your amp to your speaker. Try it! Thanks for writing, Bob Carver
Q: Are you selling a single monoblock or a pair?Oct-31-16
A: Hi '1970, Boy did I miss that disclosure! I should have unambiguously put a PAIR in the auction. My auction is for a stereo pair of amps. Thanks for asking, Bob Carver
Q: Robert What do these amplifiers weigh? Being that my back is not in the best of shape anymore- fused spine and such...I finally lucked out with obtaining an 11b tuner with Your John Hancock on it..so I am looking for some amps to make my Sony M9 Speakers sing...next question are you still in business making those gorgeous tube amps or is this one a rarity...thanks for your time..Bill SpulaOct-29-16

Question & AnswerAnswered On
Q: The man with big muscles holding the amplifier is me, Bob Carver. Sir with all do respect to your knowledge and contribution to audio.... I m having difficulty seeing them. Um, the muscles. You ARE flexing them correct? Lol. Have a wonderful holidays & I ll toast to you & your families health. Cheers. BrandonNov-21-16
A: Hi Brandon, I really have medium size muscles, but I felt good that day. The sun was shining, the bugs were not in my teeth, and my system sounded absolutely perfect that day! No flexing except to hold the amp against my waist. Thanks for writing; I thoroughly enjoy your wry wit! Warmest, Bob Carver
Q: Hi Bob I am a novelist at best but love your stuff and will have some one day. I have a chance to buy a Eico hf 89 at a good price relying on my research. Your opinion and advice would be greatly appreciated. Thanks AJNov-21-16
A: Hi AJ, Grab it while you can and never let go! The Eico Hf 89 is an absolute a beauty in making great sound. You will love it, I promise. Hope this helps, Bob Carver
Q: Hi Bob, I happen to own a Jbl Paragon and I was wondering do think these amps are to much for that speaker. Thanks for your time and for all you've done to help people enjoy quality music in their homes.Nov-19-16
A: Hi '527, When I was in college I worked at Seattle Radio Supply after school. We carried Marantz, JBL, McIntosh, Fisher, Heath, Citation, and several others lines, even including Electro-voice. I clearly remember listening to the mighty Paragon with the largest amplifiers we had at the time. Those were all about 60 - 75 watts per channel. The Paragons could play LOUD on just 70 watts from the Marantz 9. The Paragons sport the biggest and most robust drivers JBL made at the time for home audio use; they can easily stand up to my amplifier provided you use care and you should make certain the speaker fuse is properly installed. Let 'er rip! That said, It will then play so loud and with such ease, that you will definitely find yourself in Audio nirvana. BUT . . . they will play plenty loud for any rational human being with a "mere" sixty watts. Bottom line, not too much, but not necessary either. However, sometimes it's nice to have overkill and conspicous consumption, and other times it can be nonsensical. Your choice. But have fun no matter what! Warmest, Bob Carver
Q: Hoping for some insight! I have a pair of McIntosh XRT28s, rated to 1200 watts RMS. 4 ohm, 88db efficient. I know some people scoff at the Mc speakers but I like them. They do round the top frequencies off (above 15k) so I have to be careful to not have an amp that does that too. I was using a Burmester 956 amplifier and while it sounded very good, I need more watts for more headroom and dynamic peaks. I've been debating Parasound JC1s, Plinius 301, maybe a Sunfire 600 Signtaure...how do you feel these might work with those speakers? I listen to mostly rock, some metal, and like to enjoy some volume (but not at the expense of quality). Thanks!Nov-18-16
A: Hi 'prises, Since you need more power, and I know that we can never have enough power, I would vote fort he big Sunfire. Not only that, but it has a sweetness for that beautiful McIntosh line source. In addition, it has two outputs, one is called current source, the other is a voltage source output. This lets you use one for the woofs, and the other for the tweets. Trully great sound. Yes, the Sunfire is the one to use! You literally cannot go wrong! Hope this helps, Bob Carver
Q: Great to have you still building the baddest amps on the planet. Always have loved your work. Wish I could get a pair. I'm just finishing work on 4 consecutive serial numbers Clair 700 Series II's and maybe I'll sell them to get a set of these. You inspire me when I build stuff. Thanks Bob, here is a pic of my latest. (700 Series II Clair (White Oak Audio guts). Who says we don't have hero's anymore. PerryNov-17-16
A: Hi Perry, It does my heart good to hear from you, I tried to see your 700s but could not download the pics. Try sending them to bob dot sunfire at gee male dot come. I'm pretty certain that will work. I bet your Clair 700s are super sweet amps . . . I know that building an amplifier is more fun than almost anything! Honest. I hope you are having as much fun as I do when I'm building, I actually take my brand new shiny amplifier and put it at the foot of my bed; when I wake up in the middle of the night, I can then gaze at it for several minutes. Sometimes I think I get carried away with emotion! Oh well . . . Thanks for your gracious thoughts, best wishes and warmest regards, Bob Carver
Q: Hi Bob, I love your stuff. Is this the same pair of amps previously listed (now relisted), or another set of the same? Thank YouNov-17-16
A: Hi 'stan, These are another set, NOT relisted. One of my many character flaws is that there is a bit of a lazy streak in me - I used much of the same text from my previous auction. Excellent question, though; I can see how it would be confusing. Warmest, Bob Carver
Q: Considering the cost of good tubes these days, do any other manufacturers offer a feature similar to your DC restorer, which allows tubes to last decades without negatively affecting the audio? Nov-17-16
A: Hi 'center, That is a great question! As far as I know, no other manufacturer currently uses a DC restorer. Long ago, in the 1950s and 1960s, vacuum tube television receivers used a circuit like this, though not to allow output tubes to operate at substantially reduced plate dissipation, but to allow the complete DC component in the video signal to be accurately delivered to the picture tube grid. This feat allowed large black parts of a picture to be a true black, not a washed-out gray and similarly allowed large white parts to be sparkling white without a dingy "yellowish" tinge. The DC restorer I use for my vacuum tube power amps allows the output tube control grid to receive the correct signal with an almost perfect DC (bias) voltage throughout the entire signal swing, thereby substantially reducing the need to run the output tubes hot in order to keep distortion low. I suspect that this idea will be copied if it hasn't already been. That happens to me all too often, and I'm used to it! Oh well . . . Thanks for writing in, great question, hope this helps, Bob Carver.
Q: God bless mr Bob Carver!!! Love you DavidNov-16-16
A: Oh wow David! What a treat to hear that. Now my day is being made twice! I feel better than Clint Eastwood. Thank you from the bottom of my black heart (just kidding)! Warmest, Bob Carver
Q: HI Bob, listened to many of your videos. Encouraged many audio enthusiast to listen to you. You may have heard of Preston Nichols. He actually bought some of Tesla's radio equipment. He is an electrical engineer, not to go into his extraordinary history, in his retirement he sought out HI-Fi audio exploration with tubes. He had already broken many theoretical boundaries in radio transmission using tubes. He found quantum physics to be a reality in the audio spectrum. Not to give away any secrets, what have you discovered in this realm of vibration resonant transmission? Sorry the bid is over what my salary is for the year. EnjoyNov-16-16
A: Hi 5mar, Since I'm a physicist with a love of audio, I must have run the gamut of things to discover, and quantum physics is definitely one of them. Nothing as specific as vibrant resonance transmission though. You have definitely made my day, I would love to get my hands on some of the old equipment he used back rhen What a treasure that would be!

Question & AnswerAnswered On
Q: The specs, sound like a Lafayette 550 with more power? Regards, JohnDec-18-16
A: Hi John, They do? Wow, I had not noticed, but now that you mention it, perhaps they do! Massive coincidence. But as it turns out, I do own a '550, and it is one of the best sounding vintage amplifiers that I have ever listened to. Looks like I'm in good company! It was almost certainly designed by my hero Stu Hegeman - I have not looked at it for almost two years, but it is time for me to hook that trusty '550 up again. LATER: Well, it does sound nice, very sweet, but not enough power, especially in the lower midrange, at least not for me. At low levels, though, it can be pretty spectacular. Warmest, Bob Carver
Q: Hi, How much shipping cost to Thailand? Thanks Kind Regards SomkiatDec-18-16
A: Hi Somkiat, I wish shipping to you were not so expensive. But it is not too terrible. All the way to Thailand will be approximately $582 USD. My friend Peggy, who used to work in Thailand with a famous dance company, is rooting for you to win. I, on the other hand, must root for all. Thanks for writing in, Bob Carver.
Q: Great pics of the underside of the amp. One question though, would it be too much to add a few posts and cap nuts to the power supply boards to secure the B+ filtering to the chassis instead of a few blobs of silicone seal on the parts? I dont think even Sanyo or Lloyd's did that. How would you service this? Seems out of place on such a nice looking amplifier. Dec-18-16
A: Hi '32, Believe it or not, cap nuts and a threaded stand-off cannot compare to the resilient and flexible adhesive used for holding down the power supply components. Even modern aircraft wings are now held together with flexible adhesives, rather than bolts and rivets as in the old days. If this amp were being built on the assembly line in my factory, I would use a nut and stand-off because it takes too long for a good flexible adhesive to set-up and cure. Since this amp is built by Tubular Joe, one at a time, individually and by hand, there is plenty of time. Tubular Joe made good use of the extra time here and in this way. That's not to say that a nut would not work well, it would of course, it's just that Tubular Joe's way is better. Great question, hope this helps. Best wishes, Bob Carver
Q: HI u wont to know uf the amp can work on 220 v end how much is shipping to israel THANKS AMIRDec-14-16
A: Hi AMIR, Great questions; first, yes it can be set to work on 220 v. The power transformer has a split winding so it can easily be switched to 110 or 220 volts. If you win my auction, I'll do it here so when it arrives in Israel it will be ready to go. The shipping cost to you in Israel is $228 and 27 cents. I wrote the cents separately to avoid confusion. That's $228. 27 all the way to you. Best wishes and warmest regards, Bob Carver

I'm a bit slow to the punch this time but this is the latest from Bob's tube amp eBay sales. Jan 20, 2017 a black 350 watt pair sold form $7301.
 
Question & AnswerAnswered On
Q: Hi Bob, We spoke at length awhile back. I wanted to trade some of your gear toward the first VERSION of your amp. We spoke at length about the lgreat HP and the importance of soundstaging and how speakers should disappear leaving only layers of sound. I miss HP so much that my heart hurts. I have Apogee Full Range, updated, speakers with 2 JL Audio Fathom subwoofers. My amplifiers are 4 VTL Wotans putting out 1250 watts each using 24 6550's each for a total of 96 output tubes. I bid on your amps but is it an upgrade from my madness? Many thanks Mr. Genius, Robert CicarellJan-19-17
A: Hi Robert, first of all, you have a truly great name. I miss him too - he taught the world the language we use today to describe our emotional response to a great soundstage. I do miss him, he was the greatest! If this missive has a funny ring to it, it's because as I'm typing, eBay keeps saying that I cannot say that so I find that I must substitute words in order to keep the text flowing. Your VTLs are great amps, and honestly, even though my amps are specially designed to deliver a huge soundstage (like Harry's soundstage would be delivered) with a sweetness that seems impossible, I think your VTLs are very happy just where they are! They are wonderful amps indeed. I do have a question: Since there are so many output tubes operating at relatively high idling current, I can't help but wonder how often you need to replace a tube? bob dot sunfire at gee male dot come. Thanks for writing, Bob Carver.
Q: Hi Bob, I have a question about speakers, have you heard of them? SerTech Labs Stellar. The best combination of the finest sound and super-high efficiency make the STELLAR line unique and some of the most compelling speakers on the market today. Naturally we never state or imply that our speakers are the best in the world.  Even though the very idea of world's–best is subjective, there are others that actually make that claim and list some of their speakers for about $70,000 or more.  But at less than one-tenth the cost, nothing tops the STELLAR XII.   So far, we've tested hundreds of other speakers and our customers tell us the STELLAR XII devours them all.   We agree, and invite you to listen and decide for yourself. Bob this is there sales pitch and I don't mean to bore you with a sales pitch, but I have listened to these to these speakers at one watt and they fill the room with incredible sound. I was amazed, I am interested in your opinion? Regards, John Jan-19-17
A: Hi 'boat, I had never heard of them before you told me about them, and when I found them online, it was easy to see that they look remarkable. I can actually hear them in my imagination and they do sound wonderful. Sensitivity of 90 dB is just awesome! There is no doubt in my mind that they are probably great sounding loudspeakers. It's fun to be truly amazed, especially by a great loudspeaker! Great. Thanks for writing, hope I helped, Bob Carver
Q: Hi Bob, Actually the 305m's came with the kt120,I tried the KT 150 but amps would bias up fully to run that bigger tube.

A: Hi 'phile, It says you have a question for me, yet when I look, I can't find one. This happened yesterday as well. Try asking it anew; I bet it will go through this time. Warmest, Bob
Q: Hello Bob, Your website states that the 350 has 2 line inputs: XLR (not fully balanced) and RCA. I don't see an XLR input on the rear panel photo. And, what do you mean by "not fully balanced?"Jan-18-17
A: Hi 'thes, Those are great questions for a variety of good reasons. Here goes: The amplifier in this auction has both line and balanced inputs, including an XLR. The pictures don't show this because they are some old file photos; one of my character flaws is that I procrastinate too much. I had planed to take some new pictures but waited too long and had to use the old ones. The XLR balanced input on this amp includes a balanced input line, but as soon as the input signal arrives inside the unit, it is converted to a non-balanced signal and then fed to the main input 12AX7 vacuum tube grid which is DC coupled to the following stage. This yields the very best sound, in my humble opinion, and the other control grid is thereby free to become the inverting port for the main global feedback. This approach is the very best unless one has lots of noise and hum in the audio feed, and a good home stereo would not of course. I hope I did not put you to sleep, thanks for writing and I hope this helps. Best wishes and warmest regards, Bob Carver
Q: Hi Bob, I own a pair of your Red Cherry 305m that I purchased brand new January '2014,have exactly 291 hours on the set,really not even broken in yet due to window on music listening is only in the winter due to heavy work schedule from spring to late fall,I'm a business owner of fertilizing business in Ohio or to say it owns me!!! Anyway I'm trying to figure out these new amps you have compared to the original 305m design,I know you would probably prefer to sell new stuff but think your very stable and will not make you or break you,think your a man of Integrity and greatly respect that status quo;question is are the 305m have the better transformer winding-pie wound which I hear is a pain in the !*!*!!! Believe it or not I have 7stereo systems in the house,two main systems using Martin Logan Monolith & Acoustat Monitor IV speakers,the Cherry babies light these speakers up especially the ML's Can the 305m be upgraded or a waist?? Thanks, Keith Fertig-in OhioJan-17-17
A: Hi Keith, I am very happy to hear that you are enjoying your 305m stereo amplifiers. The transformers of the 305m amplifiers and the 350 amplifiers share the same scientifically uncompromising winding geometry. Your idea of making an upgrade is not only a smart move that I recommend, it is easily achieved and can be accomplished by yourself by replacing the KT88 tubes with KT120 tubes. Then set the bias to the same bias as for the KT88 tubes, as described in the 305m manual. This upgrade will not only increase the power, resulting in an even richer, more realistic sound, but the upgrade will also reduce distortion and improve reliability. This upgrade is a win-win-win situation. Thank you for your incisive question! I hope I have provided a satisfactory answer for you. Sincerely, Bob Carver
Q: Can you sendt me shipping cost for this 2 pcs wonderfull monoblocks to norway?. And i have a last question about a small stereo tube amplifier that are a Bell 3D binaural, and i just wonder what can you recommend me to buy of resistors to this amp, metal film or carbon film? Kindly Regards Alex Jan-17-17
A: Hi Alex, Your appreciation of these beautiful amplifiers genuinely warms my heart, I believe this is the best sounding, best looking, and most incredible amplifier of all time. If I may say so MYSELF. But I digress; shipping cost to Norway is $ 578.27. As for the Bell 3D, this is a great amplifier to update and bring to a new life. Either resistor will work equally well, still, I have a small preference for the metal film resistors as they are more stable over time than the carbon units. Thank you for writing, Warmest, Bob Carver
Q: Hi, I was referred to you from another member and am hoping you can help me. I have a pair of your Silver 7t amps and one of my VU meters is not as responsive as it should be. The amp output is fine, it's obviously an issue with the needle, it's almost like there is something making it so that it can't move freely. Is it possible to repair or get a replacement meter? I have tried everyone but have struck out across the board... Thanks in advance, -ChrisJan-15-17
A: Hi Chris, No problem. Take the meter out and send it to me. I'll either fix it or send you another; I have a stash of different meters left over from units of long ago, and I'll have to go through them looking for the correct one while holding yours in my left hand. If I cannot find a new one, I'll fix yours - those meters are easy to fix. Find me using bob dot sunfire at gee male dot come. I hope this helps, Best wishes and warmest regards, Bob Carver
Q: good morning Mr. Carver, I'm so excited and embarassed to speak with you..a real legend! I'm a big fan of you: I started my own job (sound engineer and audio-visual rental company) in 1990 buying a lot of your professional amplifiers. I still have 6x pt2400, 12x pt1200, 4x 2.0. At home I have a pair of silver7, s/n 012, 3x5 tube rows, driving quad's 989. But the amplifiers are switched off since 1998. So my questions: 1-I bought a variac to give power slowly. Have you got some suggestion? 2-May I restore the bias current? 3-Have you got a copy of the service manual to sell to me? 4-I've seen in the past the silver7 filled with kt88. Any modification needed? Wich tube do you prefer? 5-Do you think I must replace some caps before giving power with the variac? At the end, I'm very interested in your new circuits on tube amps. Could we discuss about an attempt to import them in Europe (or Italy only)? Sorry for the lenght of my message, I really hope you could answer me! Vincenzo BelsitoJan-15-17
A: Hi Vinsenso, Great questions! Here goes: With the variac, bring the variac to full line voltage over a period of about 5 hours. Start by turning it up 10% at first, then 30 minutes later, another 10%, and so on in 10% increments until the full line is obtained about 5 hours later, The bias current is set to yield about 18 to 22 watts per tube at idle. I do not have a service manual, but you can buy one on eBay from any number of sellers. A great upgrade is to use the new KT120 tube from Tung-Sol. This tube is a remarkable tube with a sweet and majestic soundstage. No need to replace the caps unless one is shorted or open. This is extremely unlikely as they were very high-quality capacitors way back then. As for importing, I will ask our marketing director to contact you for that discussion, however, we already do have an Italian distributor, but one never knows. Thanks for writing; I love your boundless passion, and keep on trucking! I hope this helps, Warmest, Bob Carver
Q: Hey Bob, are you still upgrading the Citation I preamp with the famous Stu Hegeman phono stage upgrade? The reason I ask is that a couple years ago I had sent you my Citation to do the upgrade and you were gone to some sort of symposium or electronics related function, and entrusted, I think it was Jason, or Perhaps Justin, a College kid you were mentoring, I spoke with him, very polite kid, and he was put in charge of doing the upgrade for you. Well, as it turned out, he did not do the upgrade. I suppose he probably swapped out some leaky capacitors, which I was grateful for, but what I really wanted was to have the Stu Hegeman phono stage upgrade done by your hands. I left the Citation in the box when it was returned to me and it has remained on the shelf since then. Sincerely, Timothy. Jan-15-17
A: Hi Timothy, Oh no! Allowing a Citation 1 to sit fallow for any time and not listened to is absolutely a sacrilege. Stu Hegeman is probably turning over in his grave! Yes, yes, yes, I am still upgrading them. Send me your tired and your poor exhausted Harman Kardon Citation 1 and I will absolutely bring it back to better than new. My deepest apologies from the bottom of my heart for not installing Stu Hegeman's remarkable moving coil design. I will not fail this time if you send it to me. Honest. I hope I may be of service this time. Best wishes and warmest regards, Bob Carver
Q: Just wanted to say Hi Bob, I spoke to you a few times and have a house still full of Carver from the good old days.The TFM's never die!! I hope you are feeling well., JimmyJan-11-17
A: Hi Jimmy, I remember well; you are making my day; a very famous guy once said that, I don't remember who, though. I'm feeling well andI had a nice Christmas I and hope YOU have a great new year. Those were certainly fun-filled days. TFMs forever! Best wishes, Bob Carver

Question & AnswerAnswered On
Q: Hey Bob, Thanks for your response, I am going to bid (and hopefully win these bad boys.I saw in another post that you had a way to balance the output better on the C 4000. With new amps I am going to want to optimize the system, and since I am using your wonderful C 4000, can you share with me the mod? Also is there anything else that I should do to the trusty beast while I have her on the bench? Thanks so much, for your continued kindness, BruceFeb-24-17
A: Hi Tuninfork, Of course, I can, the intrinsic output impedance is very low on the C- 4000, however, there is a buffer resistor on each output which will seem to affect the balance (It doesn't really of course) when you drive multiple units because each loads the unit according to its input Z. Simply replace the buffers with a value ten times smaller than the factory installed unit. That will do the trick. Thanks for writing in. Best wishes and warmest regards, Bob Carver
Q: Hi Bob, I have been a fan since the cubes, and have owned a lot of your equipment, I currently use a Carver C 4000 with a MC2105 to drive my JBL 200's. This is my vinyl listening system(and sometimes an iPod) While the 200's are pretty easy to drive, I haven't been able to build a tube amp with the drive to make these speakers sing. (I build and restore tube amps as a business) I assume that your amps will easily drive these speakers to painful levels(not something as do as much as in the 70's) After watching sales of your amps I've decided I need to own a set and am going to be bidding on these. Will you amps be happy with the Carver and the JBL's?Feb-23-17
A: Hi tuninfork, You are making my day! I assume you have driven you speakers with tube amps from work, so you understand the improved sound that tube amps can deliver. It also sounds that you need more current and voltage to really make them light up your room. These amps of mine are just the ticket for you, as I have designed them to completely drive down to 2 ohms reacive, even actually slightly below that to about 1.6 ohms. No problem for these amps. Honest. As for the Carver's and the JBL's, again, no problem. Best wishes and warmest regards, Bob Carver
Q: Too bad you wont make a lower power version of these , (around 120 watts per} and on one Chassis. I purchased an HK CIT II from one of the last surviving Engineers...I would hope that yours will sound better I would assume somewhere around $ 2000.00 that I can afford.Feb-23-17
A: Hi Fourx, I do plan to make a lower power amplifier by early next year. I'm planning for it to be on a single chassis with four huge output tubes, though I don't know how expensive it will be . . . exactly, nor just how powerful. It is so cool that you found an original from the last HK designer . . . don't let it go, it sounds priceless to me, something very precious. No need to hope that mine will sound better, it absolutely, absolutely, WILL sound better! Thanks for writing and for joining me here, Bob Carver
Q: Hello Mr. Carver, I am currently the high bidder on this auction, though I know I do not have a "Rats Chance" at winning but in the event I did, could I have them picked up. My Uncle lives in Seattle, WA. and it would help, though NOT a deal breaker for sure. Also, I have a C-4000 that I have fallen in love with and I plan to use it with my 2 TFM-15s and I have found that there is an audible decline when I use both pre-outs to drive both amps. Just wondering the best way to give equal pre out-put power to both pre-outs as I feel the pre-out signal is divided when using both at the same time thus making me increase the volume. I am old school with my speakers, like your stuff, P.L., Carver, etc. , I am hooked on what sounded best to me in early 70's, Klipsch; (Heritage) JBL, ALTEC. Thanks for your time, and most of all, your AUDIO contributions. Respectfully, Fred Hayes.Feb-23-17
A: Hi 231' , of course, he may pick them up, and if your Uncle brings your C-4000 I'll fix that up so it can drive ten amps all at once! It's easy to do and will take about ten minutes. No charge of course. Thanks for writing in and for joinong my auction. Warmest, Bob Carver
Q: You reference your amps to many that I own. Citation II, Marantz 9's, 8b, 2's, one MC3500, Fisher SA1000, etc. So if I purchased one of your pairs of amps would I have more of the same? I like my Marantz 9's and 2's the best; for punch the SA1000. Your amps are marvelous looking and your write up is great as well. What I don't want is to purchase and find out I like my other amps as well or better. I learned in the corporate world that change is not always better; although usually just different. I also understand everything is a system approach. I sometimes use my high end computer for my music server, sometimes my Hovland preamp, or my Klyne. My speakers of late are B&W 801 Series II (fairly standard good speakers). I like the sound of my MC3500 but only have one and am not willing to keep it due to it's age, size, and weight. Any info and opinions are appreciated. - Dave BFeb-23-17
A: Hi Dave, those are great questions and they definitely need a great answer and here it is: forgive the poor punctuation, but eBay will not allow a word that is preceded by a period for some reason about half the time. I also have Marantz 9's and was smitten long ago, especially when I used them with electrostatics. I wanted to make my amps better than the 9s, and I have succeeded beyond my dreams. Far more power, better low-level resolution thanks to the DC restorer as well as those huge cathodes inside the KT 120s, finally, a larger soundstage than the 9s because the spectral energy in a special part of the frequency band, the Henry Kloss psychoacoustic octave, is produced by my output transformer which I designed and is the second best output transformer in the world. But here is the best part - if you don't want to keep the amp, I'll return your full purchase price with not a single question asked. Honest! Hope this helps, and thanks for joining my auction! Best wishes and warmest regards, Bob Carver

Question & AnswerAnswered On
Q: MR. CARVER, SO GLAD YOU ARE STILL DOING WHAT YOU WERE PUT ON EARTH TO DO! DID YOU ENGINEER THE PREAMP TO GO WITH THESE YET? LET ME KNOW WHEN YOU DO! BEST TO YOU AND YOUR FAMILY WARMLY, ALL HUSKIES .Apr-06-17
A: Hi 'huskys, You are absolutely making my day! As for the preamp, I'm working on it as we speak. I plan on it being done about a year from now. It's going to be 100% tubes, including a very QUIET phono stage for MM as well as MC. I've been working on a variety of circuits, and have already picked the topology that I like the most. It's just awesome! If I may say so myself. Thanks for writing, Warmest, Bob Carver
Q: Hi Bob, I see you started out your auction with a very low starting bid! I am just wondering if this amplifier will accept other, similar high quality tubes? Love the rich color! No doubt these amplifiers will get the best out of any speakers. What about the Apogees, which have something like a 1ohm impedance? Do you have any plans to offer your Amazing Line Source speakers on Ebay? I've read the Golden Ear award review in The Absolute Sound magazine, which describes the new technological advantage over the usual "point source" speakers on the market, so now i want nothing less, and the review said I wouldn't find anything better without getting something like the Langdorf Steinway at over $200,000.00. Another benefit, I see that they don't take up much space, and include a dual speaker SubRosa subwoofer that I could even put under my couch or on a wall which would please my better half. I hope I win the amps!!!Apr-03-17
A: Hi 'percenter, Great question, I designed this amp to accept a great variety of output tubes. You can use 6550's, KT88's, Kt120's Kt!50's. Believe it or not, it will work great with EL34's or even 6L6's. The old vintage standby 5881's will work as well. All you have to do is set the bias for .080 amps and let 'er rip! You could even try 6V6's, however, that might be stretching it a bit. If you look carefully at the pictures you will find me standing between a pair of Apogees, each with an input impedance of one (!) ohm. The big output tubes and extremely large transformers work together and are able to easily drive the big, majestic Apogees with aplomb. A walk in the park! As for the Langdorf Steinway, they are far more similar to my own original Amazing loudspeaker of long, long, ago, than my new line source. Besides, mine look better, don't you think? Warmest, Bob Carver
Q: Amazing work comrade. Its refreshing to see such inspiration and dedication. I am a maker as well, although in a completely different field. I make coffee liqueur in London and appreciate the effort involved in realising a product of true quality. I will probably loose out on this as will not have the money in time but would like to purchase your next project amp. I simply have to have one and please keep me in mind. I will be buying it to use in a cafe/bar setting. Tem www.coldandblac.comApr-02-17
A: Hi Tem, There is no doubt in my mind that you will end up with one of my amplifiers . . . I think it is thus writen! I wish I fully understood where the burning desire to make things comes from, it seems that we are all driven in one way or another. The desire does seem to spring unbidden; in my case, it called for me to build a new amplifier. After all, Bob is my name and amps are my game. Thanks for writing! Best wishes and very warmest regards, Bob Carver
Q: Bob: Is it possible to have one of your mist excellent receivers, vintage about 1984, tuned up and restored yo like-new condition? Cost no object (pretty much at least)? Charley Pearson Pearsoncs@gmail.comApr-02-17
A: Hi 'o9, Absolutely! The best man on the planet for this job is Bill Flannery; sunfirebill1 at gee male dot com. Give him a shout, he is the best. I would do it myself except I'm swamped, but Bill's shop is only a few blocks from my laboratory and we often work together on units. Hope this helps, Bob Carver
Q: Does a fork lift come with the purchase to get them off the ground lol? Bill SpulaApr-02-17
A: Hi '48, Actually, these amps may be successfully lifted by an average human being of normal physical dimensions with only the mildest effort. No sweat! They only weigh 48 lbs each, and you don't have to pick them both up at once! Just think how much a single chassis unit would weigh. About a hundred pounds, still not more than a good dance partner, and certainly a strong person could throw her/him around easily, or at least make it look that way! Thanks for writing in with such great and wonderful humor. Best wishes and very warmest regards, Bob Caver
Q: Please advise whether I can use KT150 tubes to replace KT120 tubes. Thanks.Mar-31-17
A: Hi rolling-drolling, Yes, you can. Just plug the new KT150s in, adjust the bias for 0.1 amp (100 ma), and away you go. That's all you have to do. I'm glad you asked - many others have asked the same question. I'm happy that the answer is easy and universal. Best wishes and warmest regards, Bob Carver
Q: Hello from Kansas City Missouri. I'm Rob Butterworth. I bought a pair of these incredible amps a couple years back and recently one of the KT120s went bad. It will not bias, has strange white coloring and a crack accross the top of the tube. I"ve never encountered this with a tube but there it is. I have no problem paying for the single tube but I did want to ask you as I remember reading that you said you have good stock of these tubes....This way I don't risk anything with Amazon. They have one for $97.00 so I'm happy to pay you. Just wanted to ask you first.. Thanks in advance. Rob btw I'm saving to buy a pair of your new line source speakers....WOW those look great!Mar-31-17
A: Hi Rob, The tube is guaranteed for my life as long as I'm alive. Send me your address and I'll send you a new one. The tube seems to have developed a crack, air leaked in and turned the "getter" white. The getter is the silver inside the tube and it's designed to grab onto random, loose air molecules and prevent them from impairing the operation of the tube. (Which requires a high vacuum.) By the way, the amp will work just fine with a tube missing, so while you are waiting for the new tube to arrive, you can take it out and continue to use your amp with a missing tube making it a five-tube amp instead of a six tube amp. Sorry 'bout that bad tube, but thanks for writing! Bob Carver
Q: Hey Bob, Hope you are doing well. Big fan, always had a dream of owning one of your tube amps. Love the silver seven with all those tubes I was just wondering if you knew or could recommend someone who rewinds transformers or can give me a lead on an orphan output transformer. I have an old Scott lk-150 that was poorly modified by my dad so Im sentimentally to it. It developed an occasional hum, I think the caps were going bad and it looks like my dad didn't insulate some of the leads on some capacitors so voltage may have arced so my cousin knows a a repair shop in Houston so I brought it to my cousin to get it fixed. My cousin listened to the amp and loved it, he keep listening to it instead of getting it fixed. It had a catastrophic failure. So when he finally brought it to the shop, the repair tech said it's output transformer was shot and need to be replaced and he knew of none with those spec so it was junk, Any help appreciated KurtMar-31-17
A: Hi 'star23, If you send me the dimensions of the output transformer ( H X W X D ), just approximately, as well as the output tube type - it will probably be a 6BQ5. a 6V6, or a 6L6 - I will be able to figure out a good transformer and tell you where you can find one. Sounds like you will then have a great amp new caps, new tubes and away you go! This will be easy to fix. Best wishes and good luck, Bob Carver
Q: Hi Bob..lm sorry about my past questions... honestly l was very skeptical about the price of those (expensive for me) beauties and of the real great Bob Carver being in eBay... Based on the challenge you had against Stereophile's? best audio l bought my first and only system which still sounds so good and l will always treasure...a Carver TFM35X...CT-6...SDA-360 CD and AL-lll Speakers...and although very modest l became very fond of You and your products...l love my system Bob and l only wish l've should bought another TFM-35X back then because when l turn the volume half way up it starts to cut off...and someone told me the speakers require more power....so l was looking in eBay for another TFM-35 to pair them as Monoblocks...Can advise me what would be the best way to go?...(l just hope You are the real Bob Carver)Mar-31-17
A: Hi '4me, The first thing to do is find out if I am the real Bob Carver. I'm going to pinch myself and if it hurts it's really me. Ouch! ! Well, I guess that does it - it's really me! I'll do some research and come up with some good advice. I'll look out into the world and find out what seems to be available, I'll get back to you after the auction is over, or better yet, you can contact yours truly. bob dot sunfire at gee male dot com. Not to worry, we can find a great solution together! Warmest, Bob Carver
Q: Can the winner switch the color to black? "She who must be obeyed" has told me that red is unacceptable in our décor.Mar-31-17
A: Hi 'thes, No sweat, you can have any color as long as it's Red or Black. I understand fully! Thanks for writing in, Best wishes, Bob Carver
Q: I will give you 2300 PayPal direct if you could pull them. I ll pay for shipping as well. I really don t want to wait for the auction to end, you could save the fees from @bay as well. Thanks Matt 512-788-3393Mar-31-17
A: Hi Matt, I would love to take you up on your offer, but it may be that your question is an old one. However, out of fairness, I must finish this auction. I am very happy that you are interested deeply in these amps, my pride and joys. Keep your passion and please stay in touch! Warmest, Bob Carver
Q: Is the HR-895 4 ohm stable?Mar-31-17
A: Hi 'prairie, It's even better than a mere four ohms - it's completely stable down to one (1!). Four ohms is a walk in the park! Thanks for a great question - I bet many have the same thought! Bob Carver
Q: I live in Snohomish. I assume local delivery is not a problem!Mar-31-17
A: Hi 'redhorse, Absolutely no problem! Come on over and pick it up when you win. Best wishes and warmest regards, Bob Carver
Q: why are these mono blocks selling for $20.50 ??Mar-29-17
A: Hi 4me, I think it's the current bid for a 10-day auction. Warmest, Bob Carver
