Does anyone have any drawings of this amp (old).
I've got it operating but have a hiss in the output.
There are 2 daughterboards on the output. I assume the first is the PWM creator and the second is the final drive?
I have one low side output in and one hi.
Low side is getting hot. If I remove the "PWM" board it does not get hot. However drive looks ok when board is in.

How can the FET get hot if the drive signal is good?
Post a photo of the high and low drive signals, preferably with all FETs in the circuit.
