OK.... So Far Ive Changed 4 -10 ohm resistors that were checking @10k,
and have one channel working flawlessly

Ive narrowed the left channel down to the main input board on the rear of the unit ..there are three NJM4565LD audio output op amps the one for the left channel is checking bad... Ive ordered all three IC's ...All voltages on the main board are rock solid for the three different supply lines, all finals are good
Hope this fixes the amp ,, wish me luck see ya , epilespaul
