So this amp came to me with the complaint of low output and overheating. I found 4 swollen rail caps so I replaced them. I have checked the drives and followed the audio signal through the amp with my scope all the way to the speaker terminals and I can’t find any issues.
The power supply produces +57.2 vdc and -56.7 vdc. The 10 rail caps are rated at 63wv.
I checked the regulation on the power supply and I can see changes in the duty cycle with amp under load so I can assume the power regulation is working as it should.
What else should I check?
The amp is stone cold. Granted I haven’t driven it hard.
