model GM-X962, mosfets all burnt up, replaced them and repaired pcboard at
B+, low volume is ok but when turned up ( on the amp) it distorts, then,
one of the mosfets gets hot and shorts, ( Q905), and never draws much
current, 3-4 amps ? when its running on low volume, 750 watt, I'd think it
would draw much more even at low, all the bias resistors ohm ok, not sure
where the problem is and not my forte', any ideas appreciated, the
mosfets were Q905,6,11,12,13 &14
