The amp has a heat distress situation. Refurbish output devices, remove and reapply thermal paste.
Also, after the refurb, do the bias adjustment and make sure the fan is spinning normally. Clean vent ducts on the side to assure proper ventilation. Also, ODEP is linked to overloaded outputs with too low Z speaker network. Respect loads.
