Hello all. I recently acquired some carver gear. An M500t amp and a TFM 35 amp. Looking for some direction on the M500. I understand it’s a dual voltage unit using low and high voltages on the rails. My issue is the relay doesn’t close upon power up. I’m leaning toward the op amp or something in that circuit. All the rectifiers check out good but I’m only getting around 30v on the low V side. Not the 40v it’s showing in the manual. The relay is good as I have supplied 24v to the coil to test it. I know these amps are different than most I’ve worked on but I’m ready to tackle this one. Thanks in advance for any input and I look forward to interacting with all of you. Cheers.

Newbee here,,,,, looking forward to learn what all this site is about. Had a Carver system 25 years ago ,,,,, now putting several Carver systems together for my own enjoyment,,,,, hope I'm not to late LOL🤕

Just saying hi, I run a carver m 500t asy amplifier for a pair of Klipsch cf3. It's the best amp I've owned so far!

Now working on a MXR130 with no power, just Carver lights up, after about 10 seconds after turning on the power transformer will make a pulsing noise. There was no shorts found in the amp or power supply ckts. I did check C203 on the turner board which I had in the previous units were shorted. Not sure where to go from here and need to estimate to the customer.

Hey gang, My first "good" piece of gear I owned was a Carver TFM-15. Tons of love and nostalgia for that piece that's been gone for decades. I had a buddy give me a TFM-35 in good working condition that I plan to recap and clean up. I've missed those dancing meters! I'm looking forward to taking a look around. I'll post some amp photos once I'm able to!

Hello all, My name is Douglas Thompson I am an ISCET certified electronics technician. I live in Tacoma Washington. I have been working on electronic gear for over three decades. I was teaching electronics theory at Clover Park technical College for over 4 years, and I was a field warranty technician for Carver for around 6 years. I still have and work on alot of these amplifiers every week. I am at the moment working on a pm1.5t that the entire fan assembly is missing, so I am trying gto find one to put in it.l

I remember the day and all the music we would listen to some needs help and show me how to set it up if any one is cool about the help at my house in eastern washington

This was his shop stereo, and he was an Excelsior Henderson motorcycle guru for the last nearly 25 years. I knew Carver was good from back in my youth, and if my great good friend Jamie had it I knew it was worth having. I'll be re-socking the Vandersteen Model 2's and refinishing their wood, looks like they got wet at some point since 1989-1991 when they were new. I believe there are some recommended things to do to the Model 1-0t amp and the Model C-1 Control Consol. There's also a TX-2 receiver. I'll be giving these to my daughter's family so they can enjoy it as Jamie and everyone else we knew did.

Looking forward to sharing knowledge and ideas. I’m retired EE with a passion for Phase linear Amps. Some day would like to own either 700 II or Dual 500. Bought a 400 series I and II many years ago (1990’s) Both blew fuses so needed output transistors. Could find the PL909’s do used any old non To3 the local shop had. Kept blowing fuses after a while. Got smarter as I got older and ordered M15024’s mixed with PLs. Finally went to all 12 15024 in each amp which resulted in better stability. Tried to bias the amp and shorted/exploded a low Ohm resistor across the back of the T03 connector with the VOM probe. Replaced it and now waiting to unbox it all after moving and starting again. Oh well!

Hi, I am the owner of Infinity IRS Beta as well as other Infinity speakers. I am contemplating Genesis II

Hello to all! Like most of you, either you inherited some type of Carver gear, bought some Carver gear because you heard it was very good, or actually saw it working before your eyes. Mine being the latter of the three. My experience goes back to the mid 80's when my best friend had a set of 901's in the Army barracks (top floor) at Fort Polk (North Fort) with a 1.5 hooked up. My my, I'll never forget the roof lifting when he turned it up. Very memorable. Fast forward to 2024 and me picking up a M500t off of the bay. I purchased a new face plate, but my real issues are the left Side Cap (cosmetic damage) and the front glass (also cosmetic damage). Are there any alternatives for replacement or refurb services, such as polishing out deep front glass (plastic?) scuffs? Are parts still available? Thank you from South Florida, Fort Lauderdale area.

Hey everyone. Im Randy. Bob has always been my hero. I love how he started out making stuff the small guy could afford, yet it sounded like the top of the line. Many heavy hitters in the industry lost in blind testing to his creations. Anyway enough about that. I have been extremely sick I am a bit better now, but I was Death bed sick. Started in 2006. I’ll just say I was taking enough medication to kill a large horse my pain was so great I begged God to let me die. I had stomach issues , migraine for 25-30 days non stop neck and back pain. I now have 13 plates, 26 screws 2 rods and a clasp holding my neck together and had to have every tooth removed due to bone infection. So I am much better now. It just took the Dr so long to figure things out for me. This Bob Carver…… wry compassionate. I would get on an email with Bob. He was so kind and polite and even though I could barely string a sentence together or say anything coherently, no syntax at all….this kind man would talk to me. What I never told him was that I contemplated suicide because the outlook for my life was dismal and seemingly without hope. I was bed ridden for nearly 4 years and Bob would answer my phone call and speak soft kind words and because he showed so much grace. Well my goal was to build the mono block 350 amps. I can tinker but my goal is this, Bob knew I didn’t know how to build an amp and now that my health is much better I want to learn how. I do want to thank Bob cause I wanted to take enough medication to end things. Bobs kindness helped in my decision not to…..more than once. So, first I want to thank Bob and say what a great person he is. And secondly, hello Bob Carver fans. I hope to learn during this journey, to learn from all of you how to do fulfill this dream. I have two chassis and the pre amp tubes and the electrolytic caps and most other parts. Any starting advice I’m all ears.

That is a problem for many sealed pots. Simply no way to get to the tracks to clean them. This PSE studio 1 had 3 expensive noble cast aluminum pots ,2 in the tone control circuit plus volume The balance control had a open area on the side for access but in most cases you have to unsolder many pots and take them apart and open them up to do it properly

Hey all! Thanks for the warm welcome! I'm working on four (4) systems, 2 have three (3) TFM 55's sledge hammers for the bang and umph, one has a CT-29V and the other has a CT-28V for directing traffic. The third has three TFM-45 high head room bangers, it has a C-16 for directing traffic and the purpose is to well,,,, see how it performs against the other two,,,, blame Roland for that lol The later is umm,,,, well and please don't be upset, is a bit of a hodge-podge to be honest. Basically its an old Toshiba mini system that's in the process of getting two (2) TFM-35 framing hammers fitted to it to replace the tired amps that came with it

Patience and scouring eBay will eventually yield the Carver Autosound system dreams are made of. It took over two years to create the a/d/s system I used to have in my Odyssey…

Perhaps you could list the equipment that you have and we could walk you through how to set it up.

Greetings. Thanks for the add. My dad owned a burglar and fire alarm company from the 70s - early 90s. In addition to installing alarms in high end homes, he installed Hi Fi on the side. We always had a bitchin sound system in the house growing up. I remember him playing discs (not compact, but the size of vinyl) way back in the day. Then we had CDs way before most even knew what they were. Well he passed away a few years ago and I've come across some of the stuff... Like others, I inherited my dad's carver stack: C-2 preamp, M-1.5t amp and m-200t amp. They haven't been used in many years. I'm wanting to hook up a Pioneer record player to listen to vinyl in the house. First, some guidance on connecting everything up would be great. Can I use both the M-1.5t & the M-200t? Or is it one or the other, not both. If that's the case, which do you suggest? Next my volume control seems corroded. I've tried spraying CRC Electronic Cleaner and turning the knob, but it's ineffective - lots of cracking and R speaker comes and goes. Should I try something else? Is there a replacement? Thanks for the help.

If you have cleaned the volume pot and it still crackles or you have channel drop out you probably need to clean the balance pot. I am no expert, but I use fader lube on pots and contact cleaner on switches. Both caig deoxit.

You need to test TP 1 to TP 2 - NOT to ground… same with 3 & 4.

"This couple bought a rundown abandoned house for $1.5 million and plan to make it their forever home: Take a look inside...While cleaning out the home, they found some of the original furniture, old photos of what the house looked like before, and a record player that was hooked up to speakers all over the house. Volkov found that discovery pretty exciting. 'Imagine having a house back in the day and you could play music everywhere in it from a record player,' he says. 'The record player was still there when we bought the house, so that was really cool.'" https://apple.news/AjoyndHDJQOms8_wEhzSNXQ 😎 🔊

Oh I hope not. I am a full on vinyl guy but I have at least a couple hundred CD's that I love listening to.

Hold pants guys

I see that the topic is still alive, and you probably liked it. This week I will be ordering capacitors for recap, and maybe I can look into the paint shop. And here is something to read

I mowed the lawn today, and after doing so I sat down and had a cold beer. The day was really quite beautiful, and the drink facilitated some deep thinking on various topics. Finally, I thought about an age-old question: Is giving birth more painful than getting kicked in the nuts? Women always maintain that giving birth is way more painful than a guy getting kicked in the nuts. Well, after another beer, and some heavy deductive thinking, I have come up with the answer to that question. Getting kicked in the nuts is more painful than having a baby; and here is the reason for my conclusion. A year or so after giving birth, a woman will often say, "It might be nice to have another child." On the other hand, you never hear a guy say, "You know, I think I would like another kick in the nuts." I rest my case. Time for another beer.

They restore/refresh, just like any other amp..., I recall that thread from @Carlton8000, or another thread, that he (or someone) recapped and refreshed the m240's he had. I've found that the "background noise" or a good portion of it, for me, was actually road noise, or noise generated by the car/cabin acoustics..., I only did one car audio build, when I was in my 20's..., so today, with all the sound deadening, and other things one can do..., I wonder if it's as bad. I have in my garage, a full system, brand new, that I picked up for my F150..., pioneer head unit, infinity cappa speakers for all four doors, and an infinity kappa sub... It's one of those projects I keep putting off. But I know that one thing I must do is put in a lot of sound deadening in the doors, where there's lots of flex from the increased throw and air movement of those Kappa's. I don't think I'll go so far as to deaden the floor of, I'm too lazy to pull out the seats, and carpet, to add it.

Welcome, @Bobh, Glad you found us. I'm not a tech, but there are some here that may respond. Just a heads-up that this is a volunteer community of Carver afficianado's and fans..., not really a tech support site - although there are many technical threads of work, restorations, refreshes and repairs for many many Carver components - that's what the volunteer aspect is. We welcome you to start thread on your repair and contribute to the community with your diagnosis and repair. That will likely get more volunteers to pipe in over the next few days/weeks. Most of the techs that are members here are in business, and don't visit that often - they are just swamped with Carver and non-Carver work as I understand it. There are some hobbyist techs too that are exceptionally skilled, they are likely the first to respond, if they can. FWIW, the MXR-130 is a beloved receiver, and there are many examples of restorations and repairs in the forums. You could browse the receiver section, or use the SEARCH function - that will also help guide your research..., beware, there is a LOT here, and search will give you lots of threads to peruse..., and may take time. Again, welcome, glad you found us, and enjoy the deep resources here in the threads. Oh, btw, do you have the docs and schematics for the MXR-130 to work from? If not, check out the manuals library (top of page, main menu "Manuals and Specsheets".

I promised this a while back, and actually completed it in October with my audio buddy Travis. The initial question - What sounds better, SACD or DVD Audio? I happen to have three (3) different albums in both formats, AND I have all three on CD (FLAC) as well. I will start by saying that this sounds like a fun challenge, but I assure you, it was anything but. I found it difficult, annoying, and frustrating AND it had the added bonus of pretty much burning me out on these albums. In fact, I was so annoyed with the whole challenge that I neglected to even write it up here. Then a couple days ago, @MLB111 kindly inquires about the results. Shit. I suppose I should publish them, if for no other reason that to dissuade anyone else from venturing down this path. To make matters worse, I cannot locate my original notes - but I can remember a lot of it, so I enlisted my son’s help (he’s just getting in to the hobby, and starting to learn the ins and outs of high quality audio). I’m going to break it up into 3 parts - one for each album, mainly because it’s tedious and exhausting, as you’ll soon see. The system - Oppo 105 to BillD C1 to Silver 9t pair, to NHT 2.9 speakers. Kimber and MIT ICs, and MIT Terminator 4 speaker cables. The album - The Nightfly, by Donald Fagen - SACD, DVDA, FLAC. Whenever I do something like this, with media OR gear, I tend to listen to the overall presentation of course, but for the real substantive measures, I tend to focus in on the smallest, most subtle details I can find in the recording, and compare those details - wether it be between speakers, amps, or in this case, SACD and DVDA. * I cannot stress this point enough before I continue - the differences between these discs (SACD & DVDA) are so subtle and so slight that even identifying them was exceedingly painstaking. Further, these differences would most likely NEVER manifest in normal listening and comparison * For Nightfly, I found the most differences in two tracks: Track #1, I.G.Y., and track #5, New Frontier. #1, I.G.Y. = at the 52 second mark, right as the intro ends, and the trumpet fades and the vocals start, there is a very slight cymbal that is completely different that the prior cymbal cadence. It’s one strike, slightly left of center and a couple feet behind the speaker plane. The same cymbal strike happens again at 1:25, 2:10, and a few more times later in the track (sorry, I didn’t feel like listing them all). This cymbal is more prominent in the DVDA. It is a bit more “buried” in the SACD version, and not as defined. At the 2:08 mark, there is a snappy bass “flurry”. The SACD presents this with a tiny bit more “pop”, and a better “edge” the the string plucks. As I listened to this track for perhaps the 20th time in this sitting (ugh), I turned to my son half way through and said “is that a tambourine ?” I have listened to this track many times in the past, and I don’t EVER remember a tambourine. Back to the start of the track, and sure enough, no tambourine. It actually comes in at the 1:28 mark. It’s subtle, and EASILY mistaken for a cymbal. The DVDA does a better (slightly) job of defining the individual cymbal-ettes (?) around the circumference of the tambourine than does the SACD. #5, New Frontier = At 1:30 (and again at 2:40) there is a distinctly different guitar sound solid.y in the left channel. It’s tone is so different that it is almost distracting. The SACD did a better job of blending this into the overall presentation - However I’m not positive that’s a good thing, so take it for what it’s worth. In the intro, there is a cowbell in the percussion. On the DVDA, it sounds more like a cowbell - on the SACD, it lacks some of the “metallic” overtones, rendering it almost more like a wood block, than a cowbell. There is also a harmonica solidly in the right channel in the intro. On the DVDA, this harmonica is considerably more forward and distinguishable. On the SACD, it is markedly buried in the mix of other sounds in the right side of the soundstage - THIS is the most significant difference in the two discs. Overall, the edge here goes to the DVDA - the subtleties noted above, and a very slight edge in overall clarity and separation of the many instruments is the reason I feel the SACD comes up ever so slightly short. Again, I cannot stress the small measures here - it literally took hours to determine the differences. As for CD and/or FLAC, the differences there are significant - width of sound stage, detail in the specifics listed above, and overall dynamics give a clear edge the either of the high res formats over CD or FLAC.

My take on offline: You can access any titles that you have downloaded to your device. Does your Tesla have a hard drive or SSD? So - if another family member is 'online' in your home System, you will be able to listen to anything you downloaded while in your car. (Vice Versa)

Welcome @Rek. Glad you found us. Hard to say if the Carver pieces you have received were ever refreshed in the recent past or not. But in general, these items, if untouched since they were new, or if they were in a challenging environment (a dusty shop?), it's worth having them fully refreshed and adjusted back to new. Many here send their Carver gear to Greg ( @Nahash5150 ) proprietor of Nellion Audio, in Hersey, MI. I'm sure others will pipe in with other questions and recommendations. Again, glad you found us! There's a lot of information here, hope you post a few threads and stay a while. Welcome!

'AI Is Totally Safe And Development Should Continue Rapidly,' Says Totally Genuine, 100% Human Scientist

I am the original owner of two Carver M-2120 car amps which I ran in my 1991 two door Ford Explorer. I took advantage of the built in crossover via the following set up: Amp one was used with four JBL Grand Touring 5203 speakers (mid range and tweaters). Amp two was used with a MTX 10" subwoofer box which sat in the cargo area of the vehicle. I loved the amps enough that I removed them when I sold the vehicle in 2001 and still have them sitting in my house...wondering what to do with them since I am not aware of anyone who restores car amps? The amps have plenty of power and sounded nice, although, maybe a little loud in the background noise department...maybe that could be resolved with some upgraded electronic components?

In order to advance to Member, we expect a certain amount of activity to evaluate their willingness to be a part of the community. The post count required to advance to Member is 100. (If you are currently a Member and don't have 100 posts, you will not be 'demoted'). A Member is considered an active participant. They have nearly full access to the site and its resources, and can progress in rank and earn medals by sharing their experiences in the audio world with the Site. As time goes on, a Member can eventually become a Resident or play a role as part of the Administration. A Resident is a highly active member who calls this place 'home' and acts as a council member with the Administration. Residents are participants who are willing to take on the challenge of discussing site policies and provide the site with valuable resources - such as funds, time and talents. Greatly concerned for the site's well-being, Residents work hard to welcome new 'inbounds', encourage participation by starting topics of interest - and offer Karmas, skills and knowledge to all who visit. There is a special Member Role: Carver repair/mod Team Carver repair/mod Team - Chosen only by the Administrator, these members are trusted with their skill to work on audio gear. They actively take work and offer a variety of services. They are also essential to the site's 'helpful hand' in assisting those who need help with their troubled gear. Carver Repair Team members are also Residents by default. There are two consequential Roles: Retired Sandbox A Retired Member is a participant who has either shown a disinterest in the community but has not violated the rules, or one who has 'moved on' and no longer wishes to be an active member. This is not a disdained Role, but a Role for members who for one reason or another, do not wish to be part of the community's growth (for example).
