I would say it's in the POWER GUARD circuitry and it should pay a visit to Binghamton NY and see it's mother.
Chances are it's older design is just worn out. Also you maybe driving some hard to drive speakers i.e. varing resistance or possibly cross overs failing but I would lay a bet it's the PG curcuits though
