Welcome to the site. There's a lot of info here. Feel free to ask questions, it can often take time to get your bearings.

PM-1.5t are pro amps. Most have had a very hard life doing service in clubs and bars. @4krow gives good advice. Pop the cover and take stock of what you have. Be careful of what you touch. Best to let it sit for about 30 minutes after you pull the plug to allow the capacitors inside to discharge. Just in case you haven't found our library of manuals yet, look at the menu of items across the top of the home page. Click on "Manuals and Specsheets". there you will find manuals for Carver, Phase Linear and Sunfire. The PM-1.5 has an extensive section of service information and diagrams. Welcome to the site.

@Johnny_Law I hope you found the manuals. If you didn't, just look at the menu items across the top of the home page. One will say "Manuals and Specsheets". You will find Carver, Phase Linear and Sunfire manuals there.

@CarvEAR Welcome to the site. You have chosen a classic vintage pair with the C-1 and M-1.0t. There is lots of info on both of these units. But be careful, you might get the bug to upgrade them. Small note on the C-1/M1.0t combo. You may get a slight buzz in the speakers if you stack the C-1 directly on top the M-1.0t. Its not bad, and you may not even hear it depending on your speakers. Once again, welcome.

@nld Welcome to the site. There is a ton of information on the AL-III here. You should start with the Owners Manual and Service Manual. Look along the top series of menu items. Select manuals and spec sheets. There you will find manuals for Carver, Phase Linear, Sunfire, etc. Then you can check out the Loudspeaker forum. Many members had shared their insight on the AL-III's and their crossovers. You might have to poke around a bit in the sub forums to find what you are looking for. Don't hesitate to ask questions as you get your bearings. We are here to help. https://thecarversite.com/forum/76-loudspeakers/

@DanoFL, Welcome to the site. We've Got a lot of info in the MXR130. Owners manual, service manual and a few repair tip. Look around, ask questions and you will soon get your bearings. What kind of speakers are you running?

Welcome to the site.

@otisboss Wow. So much to unpack. @jazzman53 is a huge fan of the TFM-25. His posts are excellent and can be used as good guidance. I wouldn't be too worried about knockoff caps. Nichicon and Chemcon are good brands. I would hold off on shot gunning all the parts you have into the amp. I'm a big fan of first diagnosing and fixing any problems before carpet bombing the amp with new parts. Truth be told, the binding posts and RCA connectors in the TFM-25 amp are fine. Changing them may look nicer and feel better, but unless there are problems, the stock components should be good. @Circuits & Concepts is an excellent and reputable source of packaged components. Mouser and Digikey are good sources for individual components. So sorry that the upgrade information is scattered. This might be an opportunity for you to create a consolidated thread for others. We are an all volunteer site, supported by donations. Sometimes folks get fired up and post excellent DIY tutorials. Sometimes somebody gets motivated and consolidates fragmented info. It all depends on the membership. This is your chance to create a timeless contribution to the Carver community. Depending on what you find after an initial test and survey of your amp, you may want to consider sending it to a pro. It's not a bad starter amp to learn on, but you can dig a big hole if you are not careful. We are usually very responsive to questions you may have and can help, but diagnosing an amp via photos and messages only goes so far. Greg, the head honcho of Nelion idoes excellent refurb work. You can contact him directly here @Nahash5150 or via his Sound Room and even his web site. nelionaudio.com Good luck and keep up posted.

Welcome to the site. Congratulations of finding the TX-2 service manual. Not everybody finds the manuals that quickly. Hopefully your problem is a simple one. Keep us posted on your progress.

Welcome to the site @otisboss. I assume you have found our library. There is an excellent service manual for the TFM-25 there. The service bulletin understates the potential damage on the PCB. In extreme cases, the board under the resistors and transistors targeted by the service bulletin can become severely burned and even damage the traces on the back of the board. Be careful. It's easy to cause further damage when removing components in this area. Inspect the back of the board carefully for overheated solder joints and weak traces. Is the amplifier currently operating properly? If not, I would recommend doing a bit of diagnostic work BEFORE the recap and service bulletin work. It's always good to know what's broken before unleashing a bunch of parts on an amp. That way you can set expectations. Rarely does a shotgun of new parts solve an unknown problem in an amp. Even if the amp is working properly, I would recommend a quick health check prior to replacing the parts. Power supply voltages, bias setting, DC offset etc. That way if there are problems later you know if the new parts caused the problem. Good luck. The TFM-25 is a fine amplifier and well worth the updates.

Welcome to the site. There is an overwhelming amount of information sprinkled around. Anytime you start a tread, as you did, you automatically follow it. That way you get notified when anybody replies. Be persistent with Nelion. Greg, @Nahash5150 checks in regularly. Also check out his Sound Room.

I've seen vertical Arrays. Two shorter caps with adaptors. Stack em up. Screw mount on the bottom adaptor and run heavy gauge wire on either side to connect the stacked caps in parallel.

I for one, am weary of the constant droning about resistive loads, measurements, reactive loads, high voltages, etc. Measurements play a role in verifying the proper operation of an amplifier. Your ears are the final judge. ignore either at your own peril.

Inverted amplifiers such as the M-400 and M-500 are an interesting idea. Yet it didn't really catch on. In fact, I can't find any inverted amplifiers today. From your perspective, why have inverted amplifiers faded away?

@pbzka Welcome to the site. We've got a lot of free info on Carver equipment, but only have the service manual for the 6200. There is an owners manual for the 6250 which is likely similar to the 6200. The first step in troubleshooting your receiver is to determine the full extent of the problems. Does the tuner work? Do the audio connections for video work? It's odd that the phono would work fine with the other audio inputs not working. Does the remote work at all (if there is one)? Often when all the inputs stop working you will find the tape switch is in the wrong position. Judging from the 6250 manual, the tape switch must be pointed UP to allow the phono/tuner/CD/Aux/Video inputs to function. I know, your phono works fine, but did you move any switches during your test? Once the full extent of the problems are determined and cockpit error is eliminated you have a very challenging job. The 6200 appears to use solid state switching to switch among inputs. Do you have the skills and test equipment to trouble shoot this? Once you get past opening the cover and looking for burned components, you will need a multi meter, oscilloscope and a test signal generator to narrow down exactly where the failure might be. You will also need electronic skills, patience and good eye sight to read the schematics in the service manual. Receivers are a tough place to start your Carver trouble shooting education, so you might want to consider sending it to a professional for repair/restoration. That receiver is over 30 years old and may be suffering from a variety of age related issues. Try the search functions of the site as well. A simple search for 6200 turns up a lot of older posts. Not sure if any pertain to your situation, but it would be useful to review them. Good luck and keep us posted on what you find.

Oh. And be aware that this amp took a tremendous beating at the hands of Amir and others on ASR. Bottom line is that they didn't know how to test it and ignored advice on the proper test procedure. I could start ranting, but that's the bottom line.

@AudioResurgence Welcome to the site. You've stumbled into a group of people that are quite experienced the the Crimson 275. Many of us participated in a special build of the 275 back in 2018. Bob offered a kit (actually more a box of parts) where he provided guidance on how to assemble what we ended up calling the CF2018 amp. I believe it to be identical to the Crimson 275. Search around on the site, you will find extensive discussion on the build process with photos and schematics. I looked at your blog. You definitely have a factory Crimson 275 that has been seriously modified. Forgive me for lifting a photo from your blog, but there are clearly some mysteries surrounding the filament wiring and some bonus (and burned) resistors. The Zobel network on the speaker binding posts also seem to be missing. I strongly suggest not plugging it in until either the mods can be understood or removed. Here's a similar shot of a CF2018 amp that is working great. It's a fine amp. They rarely fail. I assure you that Greg at Nelion throughly understands this amp as do many site members. If Greg is too backed up or reluctant to take on the mods, you may find someone here that can help out. Good luck and keep us posted.

Wow. One or two channels driven?

Welcome @Rapid. Wow. That is a stunning pair of speakers. I'll post a link to your ad in the Found deals section.

Welcome @Dorian. The PT2400 is a beast. Many of the Carver amplifiers share their basic principals of operation. Service manuals for them often go into great detail on their design. Reading the service manuals for the M-400, M-1.5 and the PM-1.5 will provide an excellent foundation for understanding the PT2400. It's obviously different from those amps, but the basic idea of a triac controlled power supply and multi rail amplifier are the same. Also keep in mind that the PT2400 is virtually identical to the TFM-75. They have different input circuits and are likely voiced differently, but share many common circuits and components. And as @3M_Audio said, what symptoms of your amp? What kind of test equipment do you have? And most important, what kind of background do you have? The PT2400 is not the place to be learning the principals of electronics.

Welcome @Daniell. The C-1 and M-400 are a great combo. Lots of info here on both.

Welcome to the site @msave1969. W've got a lot of info in the TFM-25. Manuals, schematics and several repair threads. If you've got any specific questions, I'm sure we can help you find answers. In the mean time browse around. Remember, the search function is your friend.

Wow. Congratulations. Not many around here can lay claim to a successful CT-17 repair.

Apple Music will still rip CDs into MP3, Apple Lossless, AAC, AIF and Wav formats. I prefer FLAC. Flac is lossless without fooling around and is pretty much universally accepted. I've run FLAC with Sonos, Cambridge Audio and various Logitech devices. My preferred software has been dBpoweramp. It can get confusing to use (or maybe I'm just easily confused), but it rips quickly, retrieves album art and sets all the track, artist, genre, album and other tags properly. If you dig into the details, it will even set the file name as you please. Free 21 day trial. The about $50 to buy. I bought my copy well over 10 years ago and they are still updating it. Strongly recommend you fool around with it before ripping 100's of CDs. File naming, tags and directory structures can get tricky depending on your player. Worst thing is to rip 100 CDs only to get smart and realize you have to di it again. dbpoweramp.com
