Hey guys. I’m havi trouble with this amp here. I got it already worked on I was just trying to correct the previous work with fresh new parts. Anyway upon replacing all outputs I had no audio whatsoever. I replaced C115 & C120 audio came back on clear. After a few minutes of play it faded out. Replaced them again sound was back. Any leads what else to check to bring back audio permanently?😅 thanks guys!!

Audio is only one channel the other works fine. It’s the channel that’s pictured as you can I see I added some replacement capacitors rated the same value but appears to be burning them out.
It's been posted before but I've attached the diagram in case you don't have it.
Lift D102 and D104. Does the audio drop out?
Be careful, this will defeat the protection circuit.
Did you carefully check all of the 0.1 ohm source resistors?

I'm assuming that the 200 series channel is still OK and that you lifted those diodes.
What's the DC voltage measured directly across R122 and R222 when the 100 series channel is silent.
