So I have been poking around at this and finally pulled Q9. It tested low gain and high leakage. Replaced Q9 and the noise and DC offset is gone....
I defeated the turn on delay (removed C21) and the hum and voltage went away.
I bought a Marantz 2325 from ccheath. It was a very smooth transaction. It was also the very best packing job I have see. Do not hesitate in...
Yes but audio is delayed.
Nothing new with the cold freeze spray.I read somewhere the Q5/Q6 where for over current and could be left out of circuit for testing. I removed...
