The output FETs for one channel is heating up fast.The bias is not working.
The bias voltage goes from 0.000 and jump to 0.056 like a pulse.The pot seem to be ok.Any ideas?

Short the bias transistor collector to emitter. Do this on the main board where the 3-pin header solders into the main board.
Does that make a difference?
Has any work been done on the amp?

While check for continuity from the bias transistor to the header pins,I got no reading.
The header un-solder it self from the heat sink pad.Re solder it and that channel is ok.
One of the other channel is bad and has been work on.It puts out rail voltage on the output.I see no shorted output.
