Anyone finding the fets q200-201 faulty or intermittent?

Symptom is unit runs a few seconds/minute then starts to cut in and out, all the while emitting noise, popping and then just goes to no audio at all.

I can cool the area and it comes and goes, but there is more on the underside of the amp board. Supplies look good/clean.

edit: Swapped em out same thing. Hope its not that DSP board.

Thx in advance

Not knowing what a Q200-@01 is .
Can you post a schematic?

muting fet's on the amp board. I'm using the TH15A schematic posted from this board.
I have a feeling the problem is on the DSP board. This one is a consignment so I have a week or so. Other more pressing units of late.
Just seeing if anyone else experienced this unit's symptom.
