  1. Welcome to the site. I'm not familiar with the Genesis G200 or its relationship to Carver ribbons. But, Ed Atkins is the guy that repairs Carver ribbon drivers. He's a member here. User name is @sea.
  2. Wow. If you have got +/- 99volts where +/- 69 volts are supposed to be, do NOT turn it on again. Other rail voltages in the amp will be high. The probability of venting one of the big power supply caps is very high. The Tirac is behaving as if it is shorted. You said you replaced it. Double check that it's wired correctly. Troubleshooting will required a Variac. With a Variac, you can vary the AC line voltage down to something that yields WAY lower than +/- 99 volts. From there you may be able to diagnose the problem. If you don't have a Variac consider sending it to a professional. Further testing with voltages that high will not end well.
  3. if the relays are not engaging, your amp is likely in protection. Something has gone wrong. Suggest you start with downloading the service manual. Check the output transistors for shorts. Also check for DC offset at the outputs (up stream from the relays). This may help narrow down why its going into protection.
  4. Updated manual has been posted. @Cavscout -- Is the protect LED coming on at all?
  5. Welcome to the site. Sorry to hear about your amplifier having problems. Most carver amplifiers that "cut out" are going into protection for some reason. Very unlikely that the transformer has anything to do with the problem. In fact, the M-200 is what carver calls a Mag Coil power supply. It is NOT a standard transformer. Your amp needs a complete checkup to determine IF and WHY is is going into protection. Check the manuals here on the site. There is an excellent service manual for the M-200. It contains a great theory of operation section and a detailed check out procedure. Good Luck. Let us know how it goes. One you narrow down the problems we may be able to assist you.
  6. Selling that equipment is no small task. Testing, cleaning, packing and shipping will take time. Packing in particular can be challenging. UPS and Fedex will pack things, but they are expensive and often do a poor job. Feel free to post anything you have. Offering it for local pickup will help. I know Barry had a lot of nice stuff.
  7. Welcome to the site. Look around, ask questions. There it a lot of info here.
  8. Welcome to the site. Check out the manuals. We got a service manual for the 6200.
  9. Welcome to the site. Like @3M_Audio said, a LOT of info is available here on the site under "Manuals and Specsheets". Check with Greg at nelionaudio.com. He owns this site and can also be reached via PM at @Nahash5150. I know he had quite a few several years ago.
  10. @Evancox Welcome to The Carver Site. We've got lots of info on the M-400. Check out the service manual and it will provide a great overview of how the amp works along with trouble shooting tips. In case you haven't found it yet, the manuals are along the top of the page under "Manuals and Specsheets". The M-400 is one of the oldest Carver amps. Give us an overview of your background and what kind of test equipment you have. The M-400 is a bit of a jigsaw puzzle and not a great way to start your education, but it's been done. Give us a quick description of its condition and you will likely get tons of help.
  11. 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.
  12. 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.
  13. @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.
  14. @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.
  15. @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/
