RE: Amp turn off THUMP!!!

I tried to find a schematic, didn't have any luck. If the cause is a power supply problem, like a double ended supply and the capacitors on one supply side discharges faster than the other, you would probably hear the thump out of more than one channel, so i'm guessing the problem is in that one channel. As a practical solution, due to weight and inconvenience, leave it powered on.

Depending on the circuit, there are a lot of pieces of equipment where turning it off and on is much harder on the equipment than leaving it on. I have a Sony surround sound receiver that has, other than during power outages, been left on for about 18 years now.
