Hello fellow Carverites. My name is Conrad and I've owned Carver audio equipment since 1988. My audio equipment was placed in storage in 1995 as problems started to appear with the pre amp and power amp and I didn't have time to spend trouble shooting. I retired in 2021 and decided to take it out of storage and get it back in operation. My audio system consists of: -C1 pre-amp which I refurbished in 2022 with the BillD mod. Sounds great. -M1.5t power amp which I re-capped and tuned in 2022. Sounds great and is my main amplifier. -PM1.5 power amp which I found at a pawn shop, I re-capped and tuned in 2024. The amp was in decent shape but had an intermittant right channel caused by several cold solder joints. This is my back up amp to the M1.5t. -TX 11a tuner. I haven't re-capped as it still operates well and sounds great. -TL-3300 CD player which I am starting the re-cap process as the left audio channel has intermittant low-level crackling. -KEF 104/2 speakers which I re-capped the crossovers with capacitors from Falcon Audio in the UK. Replaced the donuts of the woofers as they had deteriated. Cleaned and refreshed the ferrofluid in the tweeters as they had stopped working due to the 36 year old ferrofluid. -Speaker cables are clones of Nordost Vahalla cables which I built myself In 2023. -Turntable is an Oracle Alexandria MK III in gloss black with a Sumiko tonearm and Dyna Vector DV-20x2 MC cartridge. The turntable suspension was rebuilt with OEM components along with a new belt and a new DV cartridge installed in 2023. -Phono stage is a MOON 110LP which was pre-owned but not abused. My music is rock, jazz, blues from vinyl and CDs. I apologize for being so long winded, my background is that of an electronic engineering technologist from nearly 40 years ago. In my early years while in college, I worked as a bench technician for a TV and Stereo shop. After I graduated from college I worked as an electrician / electronic technologist at a large steel plant. I left there in '91 to pursue a different career until retirement. I'll post photos of the audio system once I'm able to. P.S. I downloaded the service manual for the TL-3300 CD player and noticed the schematic and other pages are missing from the PDF file. I wonder if any one has noticed this and my have a complete service manual. Thanks for reading, I look forward to chatting with you. Regards, Conrad.

Looking forward to sharing sights, sounds and ideas with like-minded Carver People! Tried re-attaching My C-9 today and am having issues. Just now digging in to it. Wish me luck! HAPPY EAR (Bob in Zanesville)

Hello, all Bought decent Carver components ca. 40 years ago and enjoyed them for many years. Stuff has been out of use for a decade or more and needs refurb. I've joined here to research the options for refurbishment.. 2x MT 1.0 amps C-1 Preamp TX-11a tuner Amazing Loudspeakers (30 inch ribbon version) Links to repair shops/people wanted! -Gregor

Well, better late than never> I am a new member to the site, having just joined within the last two weeks. My name is Joe and I have been a ardent Carver fan for, well, as long as Bob Carver has been designing. I always liked his work with Phase Linear and sold his equipment in a past life as an audio salesperson. I currently have both a Carver tl3200 CD player and a Carver c-3 Preamp connected to my system (although I swamp the Carver with a Bryston MC-1 preamp). Once I accumulate the required number of points, i can post my system for the group.

Hi everybody. Hifi enthusiast since more than 20 years, I'm 40 now, already owned Cinema Grand Signature with Grand Processor 3, and finally back to a 300x2. Lot of speakers were paired with it, like ESS AMT 1B, ESS transar atd, Soundlab Audiophile 6, Zu Definition mk4 and many more, still own all of this and many more ... Today it drives Dynaudio Consequence, with Gryphon Sonata premp, mainly. Sources are Day Sequerra FM Reference Panalyzer / Krell DSP / Wadia 6 / Eversolo DMP-A8 / Studer A810 and EMT 950E. PS Audio P10 & P5 and Clear Image Audio T4 takes care of AC quality and stability. Even with Cello full system as well, Performance II (2 pairs, 8 boxes 😎 ) and Encore 150, Suite and Palette, this little Sunfire is still surprising ! It will last as my forever amp I guess, as my ESS AMT 1B ! Pleased to meet you all. Nick.

Just a quick hello from a fellow Carver enthusiast. At the present time I have a CT-7, CT-3, CT-17, and a TFM-35x (on its way back from Nelion Audio).

Hello, everyone. I've always enjoyed listening to music, but did so for most of my listening either in the car or with various types of headphones and earbuds. I did have a set of Klipsch The Fives and an SVS Micro 3000 for my living room and TV setup, but I never used them for what one would call critical listening. That all changed when I ended up buying a Martin Logan B1 speaker that was open box. It was discounted heavily, and due to my naivety, I was under the impression that I was purchasing a pair of bookshelves. The box seemed impossibly small, and I quickly found out that hifi speakers are sold separately. Nevertheless, I decided to give it a demo using my Dayton ap150 class a/b amp connected in bridged mode. Within minutes I found myself spellbound, and I fell in love with the incredibly detailed highs and nuanced/textured bass of the speaker, so I ended up returning the single B1 and purchased a pair of B2s. After bringing them home and setting them up haphazardly on the sides of my TV (too close together and not far enough from the back wall) I discovered they were shrill and lacked the bass response I had heard from the broken in B1 placed in the center of the room. There began a long journey of research into speaker placement, sources, room modes, sound absorbing treatment, and naturally signals chain equipment. I started out with a fosi audio "chi-fi" ZA stack, but there was always something missing in the sound that I was hearing. And though I tried a few different amps which made some improvement in certain areas, I ultimately struggled to find something that could really bring some heft and punch to the sound that I knew the speakers were capable of. Once I stumbled upon a Carver M1.5T that had been recapped and hooked it up, that was the day I became an audiophile. Since then, I've done extensive room treatment using DIY mineral wool panels and have obtained more than a few components, including a Carver CT23, MX130, two Sunfire HRS12s, and most recently, a few different hybrid tube preamps. I haven't even had the chance to try them out and decided which preamp I'm going to run full-time, but even just using the WIIM ultras integrated preamp, my careful setup has resulted in the best audio I've ever experienced thanks primarily to the effortless clean power from the m1.5t (and the foundational knowledge I had applied to the setup). I have massive respect for Bob Carver, his character, impact on the audio industry, and anything that his incredible mind and skilled hands had a part in. I've consumed just about every bit of knowledge and lore I could find online and I came here looking for as much knowledge and wisdom as I can glean from you fine folks. In my hunt for equipment, through meetings on marketplace or messaging sellers, I've learned that some of the most intelligent and kindhearted people are audiophiles, and it's an honor to be a part of the community. Thanks for your time reading this, I can't wait to hear/see what else the journey in search of absolute sound reproduction has in store for me

Well, I think I've sold my Infinity RS IIIa speakers. I've had them listed on craigslist and Audiogon for about 3 months. There was a guy in KS that had to have them, and then he ghosted me. I'm supposed to meet up with another gentleman when he returns from vacation. I hope the sale goes through, because I can deliver them to Osage Beach MO. That gives me an excuse to eat at my favorite BBQ joint in MO, Half Sauced BBQ. https://halfsauced.com/ Now, as much as I like my NHT 3.3s, I'm considering parting ways with them. I don't know how serious I am though. They're the main fronts in my HT setup, and if I do sell them, I want t replace them with some Martin Logan ESL's that are at least one bump up from the ones in my 2.1 channel system, and those won't be cheap. I wouldn't let the NHT's go cheap either. Like I said, I like the NHTs very much, I just like the Martin Logan ESL sound more.

Thanks for adding me to the group. I am a long time Carver owner. Bought my first Carver in the early 90s, a TFM-25. Since then I have had a HR-752, and currently have a M1.0t, M1.5t, Sunfire Cinema Grand, CT-24, CT-7, and a C5.

Good Day to all; Just joined up a few weeks ago. Introducing myself as the Old Man (and I am). I've had Carver gear for a long time now, since it was new as a matter of fact. Started buying the gear when I got out of the Air Force in 74. One of my friends had an amp and I really liked the sound of his system. I own a few now. Ive got a C500, with a C4000 preamp. I also have a M200t on the bench right now doing some repairs to it (Thanks for the manuals!) I have a AVR100 that I love for my TV room with a DTL-200 player. Collect Vinyls and have a decent Rega P3 turntable. My C500 drives Polk ES60 column Speakers and Klipsch RP8000 for surround. Not the best of the best but better than these old ears can discern. Bit of a Jazz buff and a classical nerd so I need something decent. I just wanted to ring out to everyone here and say HI!

Hello all! As the title says, I am a new member, but I've owned a few Carver amps before. In fact, I started off my audiophile journey with Carver equipment. When I was 19 years old, I worked for Best Buy installing car stereos in the early 90s. Back then, I thought Infinity and Bose were as good as it gets for high end audio. Then one day, I strolled into a small audio shop when I had some time to kill. Most small electronics shops I'd been to prior to this sold cheap stereo equipment like Magnavox, Emerson, or some other terrible brand. This shop was very different. It had an almost regal feel to it, and the music I was hearing when I opened the door was light years better than anything I'd experienced before. I was drawn to a particular section of the shop where the haunting melody of Chris Isaak's Wicked Game was floating in the air. What I heard was truly three dimensional sound, out of a pair of speakers for the first time. When I looked to see what equipment was able to perform this magic, I was taken aback by the beautiful warm glow of two VA meters before noticing the words "Carver" and "TFM-35x". That amp would eventually become the foundation of my first "real" audio system. I didn't make that much at Best Buy, so I put it on layaway until I was finally able to pay it off and bring it home. I started off with Polk speakers, and I don't recall the model, and while they sounded good, they weren't that memorable looking back. I soon won the favor of the owner of that small audio store, and he made me an incredible deal where he would sell me a pair of Martin Logan Aerius at a crazy low price in exchange for me letting him use my Best Buy discount. This is when the Carver truly showed off its chops. I was in heaven. Carver will always hold a special place in my heart because it was what led me to experience truly amazing sound. I'm very thankful that I took the time to visit that shop. Fast forward to why I am here today.. I just picked up an M-400t for an incredibly low price. I'm hoping to restore it to its full glory. One of the channels isn't working, so I'll start by investigating that. From there, I'll likely move on to replacing all of the aged parts (recap, etc). Looking forward to being a part of the community. Who knows, maybe one day I'll even pick up an old TFM-35x. Those gauges are still a piece of art if you ask me.

Hi all newbie from Yosemite National Park (South entrance). I am an aerospace machinist (CNC & Manual) I make parts for the current rockets going to Mars and the moon. Not space X, for Nasa, Lockheed, JPL etc. Just had a Carver TFM-35 restored by Nelion Audio. Using it with a Denon AV receiver, Heathkit AP1800 preamp, the TFM-35 amplifier. Through Polk Audio LS-70's. I have two Klipsch La Scalas I plan to try out just havent hooked them up yet. Hope to learn a bit from this site. Thanks for having me. Don H.

I had a wonderful experience this week I'd like to share. The story starts out badly...... earlier this week, as I was moving gear around (which I do way more frequently than I should, probably) I accidentally knocked my turntable off a table sending it crashing to the floor. The dust cover smashed into several pieces, the counterweight on the tone arm was broken off as was the cuing arm and several other bits. I was as heartbroken as I was angry at my clumsiness. I loved this turntable. It was a '80's Technics SL-D2, completely refurbished. It looked like the day it came out of the factory. I bought it from a guy, Carl, who refurbishes Technics turntables. He does terrific work. I didn't know if the turntable could be fixed. So, I contacted Carl. After I quickly described the tragedy, Carl told me that, even if it could be fixed, I'd be better off buying a replacement turntable because it would cost less. So, I I found another Technics in a local shop and bought it. Got it home, added my cartridge, and it played just fine. But, I wasn't happy. I realized what was missing was the refurbishment... the comfort of knowing that the gear was working 100% to spec. So, I contacted Carl again and asked if he would refurbish this replacement turntable, and he gave me a very fair price to do so. I drove it down to SC yesterday and got a glimpse of Carl's workshop. It reminded me of @Nahash5150's Nelion workshop....racks of turntables, and turntable parts, 90% Technics brand, test equipment, etc. Carl told me about how he can't find some replacement parts but has a guy who 3D prints pieces for him. He quickly showed me all the tests he runs. I spent an hour just shooting the breeze with him.... he was great. I asked him a lot of questions and he dispelled a lot of "myths" about turntables... a real down to earth guy. The whole experience made me very appreciative of all the experts I know for my gear... like the folks here on the CS for Carver gear. If you're ever in the need of Technics Turntable work, here's the place I recommend: https://turntablesbycth.com/

My vinyl storage is simple in my small listening room. I have an under-lit tall table with three 75 record low wooden boxes so over 200 records at my fingertips. I just slide onto my listening chair ottoman to make my record selection. These records are in my current rotation and are in no particular order other than rock, jazz and crooner boxes respectively. On the other side of the room I have a tall 5-shelf adjustable shelf bookcase with another 200 alphabatized records with wooden dividers that look like paint sticks. The poly exterior record sleeves in the three wooden boxes have the opening on the side of the record which is very convenient and easy without removing the record from the record jacket or exterior poly sleeve. The poly record sleeves in the bookcase are open on the top. Not as convenient because the open end needs to be on the top so they stay on when pulling the records in and out so the sleeve/jacket need to be removed to get to the record - certainly not a deal breaker but something to think about.

I finally got around to re-veneering my Polk Monitor 11 speakers. Did it fast, still came out good. Speakers =$100, veneer job = about $120 for all materials. Real cherry veneer, will darken with age. While I had them out, I glued the midrange magnets. I chose not to re-attach the bases. Did not refinish them. Will eventually replace the bases with stands of solid cherry .... fall/winter project.

Thought I would poke around in here a bit. Been looking for a place to freshen up my old Sunfire Signature 600.2. This place seems promising!

I'm 62, mechanical engineer and listen to hard rock, classical guitar. I owned a Carver CT-7 Preamp and loved it and had questions about Carver amps.

Hello everyone, I am new to this site, and I am an avid Carver lover. I have two Carver 1.0t in mono pushing my AR TSW-910 speakers. These speakers love the power from my amps. I also have 2 Carver cubes. One in mono running the center channel and the other in stereo running the surrounds. I'm using a Yamaha receiver as the preamp. I bought all my Carver amps new back in 1988(I think it was 1988 as it has been so long). I'm starting to get a pop when I shut the amps down, so I think it is time to get them serviced. They have been bullet proof since the day I bought them. I'm in the Fond du Lac, WI area if anyone has a good suggestion. If not, I am planning on reaching out to Nelion Audio. Thank you and I look forward to taking time to look at all the posts on this forum. Rick

Retired federal judge in Maryland. Have been listening to classical music for 60years. Own a Carver “The Receiver” (MXR-130) purchased at the Fort Belvoir PX in 1989. It now runs a Music Hall MMF-5 turntable, a NAD C521BEE CD player, and Salk Song Tower speakers.

Hello there; I'm a new member from UK interested in Carver Back in the late 80s working in an audio shop actual sold Carver amps Sill remember a night club owner complaining that the Carver PM 1.5 cut off all the time. When visiting the venue only to find out that the amp was covered in towels from the bar man... 🤣 Anyway after all those years had lots of high end stuff going back to that time stared with Urei 809 speakers and looking around for the C1 (still have my trusty Sansui record player) and possible M400 or M500 Cheers,

Not sure if I m doing this right but here goes! Yes I have a c-1 pre amp purchased new in the 80’s, a TX-11a tuner, and two M-1.0t amplifiers. All purchased new in 80’s. A few days ago I purchased an SD/A 390t reference tube cd changer from eBay. My nakamichi rx-505 is currently being serviced by a local retired sound engineer. Henk audio and video. My speakers are pioneer S1010’s which were refoamed last year by Finn Henk at Henk audio and video. To sum it up all of my equipment except the cd changer were purchased new at about the same time in the 80’s.

Hi, I'm Fernando, and I live in Argentina. The Carver brand is very well-known here. However, I don't own any Carver components. I joined this group mainly because of my NHT speakers, as I've found some other NHT enthusiasts here. Greetings to everyone, and thanks for accepting me.

The 2 subs are home made. Passive. Sunfire HRS10 drivers. The boxes are Parts Express kits, 1 cuft. Build is not quite a cube. The front is trimmed to achieve the same volume as a Sunfire HRS10 powered sub. I did not use the face piece from the kit as I disliked the radius. I made my own faces and threw away the radiused piece. The pair is driven by the PM350 at the bottom of the rack. I won't use them with the Polks, but the Maggie LRS need them badly. Want to love the LRS, tried hard. The Polks work great in the basement, but will probably live as shown. LRS prolly on the chopping block. These were my veneer guinea pigs several years ago. My first veneer effort. I've done 4 pairs of speakers in total and the subs came out the best. Veneer on all 6 sides. I'm critical and it's difficult for me to find imperfections in these compared to the others.

Hello all, I just joined today after stumbling onto this site. While I wasn't intending to look up Carver audio equipment today one link led to another and one hour later hear I am signed up lol. I have a Carver C4000 I bought new in 1980 (# 3593C). It still works fine and I use it with Hafler amplifiers to drive a pair of Infinity Q2 speakers. I did have a Carver M-400 back in the day but sold it to a friend. Who still has it. Its probably time to consider cleaning and recapping the C4000. Maybe add any later modifications if that is possible. So I'll look around at the manuals and forum posts. I'm in no rush this moment. Of course any suggestions are also welcome!

Greetings, I joined a few weeks ago when I recognized that this is a great resource to all things Carver. I friend from High School gave me a TFM-45 she was clearing out of her garage that she no longer uses. She is was a tech long ago and this was her personal amp. Shortly after hooking up the amp, I wanted to source a Carver preamp to drive it with. My Harmon Kardon Citation 17 did not seem to drive the TFM-45 as much as I know it should. So after a reasonable search, I found that the C-1 looked to be a good fit for the features I needed it a preamp. So down the rabbit hole I go. It sound great. Drive the JBL L150s very well. I found a Carver SD/A-360 CD player that was being sold to parts cheap, and I know enough to be willing to open it up and see what I can find. Turns out one of the belts turned into a puddle of black goo. That is all clean up, now to find a replacement belt. So my question is, does anyone know the belt sizes of both of the belt? The service manual only listed a carver part number. Not the size.

GM and hi everyone! Very cool site. I recently added Carver TFM24 a month ago and love it! I have cobbled together a hybrid audio and home theater. My Carver driving older Polk RTA 11T as my fronts and Marantz 6012 for my NHTs with for surround - I Tested it as best I could at the time testing each ch with a speaker. I notice my power indicator light 1 (the bottom one) works. it lights but none of the signal lights from (LED 2 up to 7 don't light up) on the vertical LED's. I welcome any suggestions- regardless of what I am playing audio or action movies LEDs do not change ... Looking to see if I am not pushing it or are they just shot and can I replace them if they are? Not the only reason I am here but that is what led me to the site. - just found your site yesterday and am looking forward learning and checking out the various threads. Thanks!

Hi All, My Carver journey started in the early 80s when a friend picked up a C-1 and one of the original Cube amps. I was blown away. I still run vintage Carver around my place and shop, a few M1-01s, a C-1, and a TFM45 in the shop. I'm here now because I have a home theater (Denon x3800h) powering a Sunfire 300x2 I bought new and recently had rebuilt by Greg Nelion, running a pair of AL-III I also bought new 30+ years ago. After all this time the one woofer has started farting on LFEs - probably due to the improved low frequency of the new x3800. So I'm hoping people here can help steer me to how I can best restore my AL-IIIs. New woofers, or just a foam surround replacement? Crossover upgrades while I'm in there? I have a full shop, and so a fair amount of electronics work there, so DYI shouldn't be an issue. Dan

weso says hello to you all!

Hi all from Arizona, I'm now retired and enjoy working on all types of audio amplifiers (tube & SS) I have 40+ years working on electronics.

Hello all, I just acquired a Carver stack (M1.0t - inverting, C-1, and TX-11a) and am looking forward to getting them all up and running, and perhaps modded as well (definitely the BillD mods to the C-1). I normally hang out over on AK, as I have only had one piece of Carver gear in years past, MX-130 which I was able to bring back to life after reflowing numerous solder joints, but sold it while I was out of work. I've repaired lots of different brands and types of equipment, though I can't do full testing of things, so I'm ceertainly not a true tech, but I do have good soldering/desoldering equipment, cheap component tester, several DMMs, and a decent parts inventory. The M1.0t was listed as non-working, and that's what I just opened up yesterday to see if it was anything obvious. I suppose I should start a thread over in the Amp section of the forums with the info, so I guess that's all for now for this thread. Just wanted to say Hi and give a little background of what I may (or may not) be able to handle whilst doing the work. Guess I'll need to wait to rank in order to start a thread....😉 John

Hello all! my name is Rudy; I found this site by happenstance as I was doing a search for service manuals for two components units of my stereo system. I have been wanting to sit back and enjoy listening to my library of music, but my work and commute time severely limited my ability to enjoy some quiet time. Now at stage of my life there have been changes. I am a recent retiree and have more than enough time to enjoy my system, which consists of a complete Carver setup. My system consists of. TFM-42 amp C-11 preamp DPL-33 Surround processor TDR-2400 dual cassette player SD/A -360 multi-disc player TX-8 tuner I paired this with. Sony PS-T3 direct drive turntable Cerwin Vaga M-100 main speakers Braun AG L200 rear speakers DLK dual voice coil downward facing subwoofer and a few other odds and ends I wanted to use my CD player, but the tray failed to open (due to lack of use) So I searched for service manuals for what I have and found most of what I needed. Now I just have to dust off my test gear and do some troubleshooting (reminds me of work) then I can finally sit back and listen to my library of music. Thanks for adding my name to this forum now I have a great source for all things Carver.

Hello all, I have a "The Carver Receiver" that I bought from Tweeter Etc (no longer). I bought the parts from Circuits & COnceptsthat I hope will return it to working order. I used it as a pre-amp for many year as the receiver allows separation of amp and pre-amp (but then you all know that.) Getting ready to replace the main amp regulator as well as the resistors in the noise reduction boad. will check back in after those repairs to let you know if the recieiver is back in operation. Best, Jon Kilroy

You are good. Each amp is independent from the other. The fact that a single C-1 is driving them both is of no consequence to the amps driving different impedance speakers.

I’ve been collecting and enjoying vintage audio gear for the last 30 years. I’m particularly fond of Carver, McIntosh, Dynaco, and Pioneer, but also enjoy my vintage Sansui, SoundCrsftsman and Altec Lansing gear.

Hi everyone , my name is Rob from Pa. I recently picked up a Carver 900 receiver. I had read about the FM tuner capabilities and had to find out what it was all about. Hooked up to some Bose 301’s in my garage and the sound is warm and powerful with great separation and sound stage. The tuner, not so much. I hope to learn some tips and tricks on this site. Thanks for the add!

Hello, Retired 9 years ago after 38 years as a computer tech. Just picked up a MXR-130 receiver that needs some work done to it. Figured this would be the good place to learn about it - currently searching for schematics. Miss the times when stuff was worth trouble shooting and repairing.

OK, that is my cue. Does a C-9 sound better than itself after recapping? I like to think of it this way. It will sound like it did when new and not so much like 40 years later. There are times when I believe that a rebuilt unit sounds better than an original, but I will say that seems to be more about some sort of synergy rather than a guarantee. The real question that I put out there is why would you use RCA jacks for a signal connection when you could upgrade considerably for another $20? The recap itself is also inexpensive at maybe $10-13 dollars. Actually pretty much of a guess there, but not over $15. There are a lot of other upgrades that can be done as such, but on one hand, I don't think that there is a large difference in sound. OTOH it still only costs maybe another $60 or something. In the end, I ask, doesn't it make sense to spend maybe $110 and get a unit rebuilt to last another 40 years? I could go on, but that is pretty much what I want to get across here. It isn't a very big investment in the audio hobby for this service. And if your good with a soldering iron, most of it could be done by yourself. I would even talk you through it. Welcome to the site

Been following Carver for more than 40 years. Completely modded an M200t ten years ago..... Which still plays superb. Next is a PT-2400.

Hello. Thanks for the group add. I'm a Gen X'er that has finally decided to bring my Boomer father's Carver stereo system back to life.

Hello Carver community. I am new to these amps and I want to learn more about them. I would like to do some repair and restoration work on these amps and I'd love to learn more from the pro's.

Just purchased set consisting of CT-17 TFM-25 . Looking forward to getting it rolling when it arrives. Thanks for allowing me to join.

Hello everyone. Gary Barnard is my name. I love audio

Just found this site, Carver fan for many years. Currently running C-4000 with Adcom 555ii, Audio Alchemy digital drive system III with Polk SDA 1Bs. Have another system I’m building and might search for a carver cd player.

It looks like Oppo’s replacement may finally be here - Marnetar. Everything I’ve read about them is positive. The 8000 uses Burr Brown DACs, and the 9000 uses ESS. Plays every disc format known to man, great build quality… https://magnetar-audio.com/elementor-4530/

Hi there, I’m Granitetop, getting crotchetier by the day, as I am getting ready to start the last season of life, I realized how much I love music after going into a hi end stereo place. Having started as a young man, joining the AF, while stationed in Europe, Germany specifically, we had the coolest places to purchase the best stereo equipment of forever. Most of you know this if you were in during the 70’s, 80’ and early 90’s, all that equipment was top of the line and Made in Japan, speakers were mostly American. We were a group called AMMO (ordinance), we all had beautiful stereos but not really knowing what we had, I bought a Carver HR-752 before leaving Germany. I had other stuff Altec 14’s Yamaha CD player like CD X-1…. Fast forward now, my AMMO brothers, kept most of their equipment to this day and are able to repair their stuff and that what brings me here, the broken Carver HR-752. Ta Da

Hi, Im new to the forum. I actually got referred here by Grok of all things. I have been looking for a service manual for a CT-26v pre amp and had zero success, so I decided to let Grok search the net for anything and it actually referred me here. I have a Carver m1.5t that has been fried for the past 20 years that I have just now got back up and running. I also have a Carver CT-26v preamp that is working well. I like to have service manuals for what I own. I enjoy looking over them and trying to understand them. Are there any service manuals available for the Ct-26v? Thanks.

I have a Sunfire d-10 that makes a humming sound when power is turned on. It does still produce sound given to it by the receiver but continues with the hum.

For those experiencing issues with the bias setting on the RAM285, the issue is likely with the burn-in effect of the circuit and transformer winding that powers the bias circuit. Many Bob Carver Corp amplifiers experience this trouble. Common complaints are: - The bias does not adjust high enough. - The bias does not adjust low enough. - The meter is not working. Unfortunately, there is no DIY fix for this. The RAM285 has extremely unfriendly serviceability. The PCB hides most components and is multilayered. Reworking the circuit board requires technical experience and proper tools. Moreover, the trouble has common causes but it may also be related to other less common troubles, so the amplifier should be fully tested to verify what the real trouble is. Please inquire with us to get your RAM285 serviced if it is experiencing any trouble.

I've been working on my new-to-me HR-772 receiver, and I could use some help. I picked up the receiver from FB marketplace for $120, which I think is a steal, but it has a couple of problems. I noticed that when I would turn up the volume the sound would get "thin", also, that the remote control would not work. I looked at the main caps and saw that they were bulging a bit, so I replaced them along with all of the other caps on the main board with hi quality caps. Here's where the problem began. Now when I turn it on, it goes in to protection mode after about 5 seconds. In that time, I can verify that the remote control works, but now the entire system goes into standby/protection mode. Does anyone know the proper voltages that should be expected out of each of the main transformer leeds, and after each power supply filter caps? I think I might be getting too much voltage out of the transformer, but it may be something I did. If anyone has any advice or information they can share about their experience, I'd be very grateful. Thanks

New Carver owner. Just purchased a C-2 Preamplifier and an M-200t amplifier at auction from the estate of a collector. Don’t actually take possession until Tuesday, but I’m looking forward to check them out. Probably need to at least do a good cleaning before I hook them up to the BW CDM7 Special Edition speakers!
