Hi,
I’m repairing an Acoustic 320 that had suffered a catastrophic failure. Four outputs short and bad burn damage to the amplifier board, several components charcoaled.
I’ve found the, quite unreadable, schematic and was able to rebuild the amplifier but for one part.
The bias transistor (Q6) has been moved from it’s position on the bottom of the board together with the pot and sits now on top of one heatsink with flying leads. The collector is wired with the red wire to the middle of a voltage divider made of two resistors that are totally burned up and open.
Has anybody the same setup and knows the values of those resistors?
Thanks in advance.
