may help to mount the amp where the PCB is up as was done in CS2000H.
PV1500 full of smoky dust still works in a church install 5 years ago, its time to bring that air compressor and bust the dust off the PCB.
I put 100 ohm 1/4w resistor on each rail on simple amps , then watch them become light emitting resistors when something bad missed replacement.
Tin whiskers , thats 25 year old fact. Still companies saving on cost use tin plating. The whiskers punch through insulators , cross PCB lands and then they recall all the boards- major bummer!
