This is as much fun as watching a good detective movie. I really appreciate how you walk us through your errors and the logic you use to work through the problem. Brilliant.
Nick, I am always blown away at your ability to zero in on the problem area with systematic thoroughness. You always deliver, your doggedness is inspiring!
I have several units of Carver equipment and I just love them! Well made and easy to work on. 5 different Amps, 3 pre-amps and a couple of Tuners. Great vid. Thanks.
I came here looking for a carver review only to quickly learn thats not what this was. I watched anyway and thank you for being detailed. My carver will arrive tomorrow
Really enjoying your diagnostic approach. Could you explain how you go about checking some of the components as you work through your repair. Keep up the good work.
Nice amp,and nice fix,love your work,wish i was that smart,i am still trying to fix mine standby transformer of mine Denon amp,but still no luck,probleby an easy fix for you.sorry for mine bad englisch.
One of the main terminals is tied to neutral. I don’t remember which (MT1 or MT2). I connected my probe’s ground lead to that and the signal lead to the other triac terminal.
Excellent video! Detailed and explanatory! I subscribed to your channel and I am waiting for your new videos, I hope it is the same excellent! Thank you!
The amp must be putting out at about 3-5 watts for the meter to show some action. To hit the upper ones, the sound is now pretty high and uncomfortable. For normal listening, I only see the lower (indicating ON) leds.

Same amp. Seems like I’m chasing the same issue.
Thank you for this!
Great fault finding, I'd admire your perseverance.
Interesting failure symptoms, but the failure itself was quite common in the power rail. Thanks for interesting vid.
So helpful. Thank you for giving me the confidence to peek under the hood.
I have one of these that I have to crack open and embark on a similar adventure. Thanks for the great vid !
Great video. Short, informative and to the point. Two 👍👍 up!!
Beautiful amp! Carver did not skimp on the output stage! All those transistors!

I had one back in the 90s Was awesome , wished I still had it and my casket-sized Polk Ti speakers and Velodyne 15 inch powered sub.
but why would that one bridge rectifier bring down all the other rails (i noticed two other independent circuits)?
How would one learn this type of skill? Any good books that someone can recommend?
Cool, well done and very good documented.

Muy buena reparación. Saludos
Complete failures are always simpler to diagnose than distortions or intermittents.
No tiene potenciometro para control de volumen?hace años vi uno asi pero no pregunte porque no trae control como los demas....saludos
Interesting video ! How did you do the triac test at 11:45 ? Was the amp isolated ? Or the scope isolated from the mains ?
One of the main terminals is tied to neutral. I don’t remember which (MT1 or MT2). I connected my probe’s ground lead to that and the signal lead to the other triac terminal.
Is the audio out of sync with the video?
Hello
Can you describe the repair of the Mackie m1400 or m1200 power amplifier?
Do you have a specific failure? If so, I could take a look at the schematic and get back to you.
It's a great amplifier
Excellent video! Detailed and explanatory! I subscribed to your channel and I am waiting for your new videos, I hope it is the same excellent! Thank you!
I've got a TFM 45 that needs a bit of work.
noticed the meter wasn't working at the end when you said everything was working as it should, just saying

Got a short, must be a cap. Odd smell, must be a cap. Fuse blown, must be a cap. Wife is being a B, must be a cap.
a dim bulb tester might have caught this right away, no?
Carver was certainly a novel designer, but I was never taken by the Carver sound.
ok
Me neither, im sure the tube stuff sounded good though.
