70's Ampeg B 115 repair

IMHO trying to repair an old DC couple power amplifier is an exercise in futility. Unless you re build the whole thing from scratch, i.e. replace every semiconductor and cooked resistor the amp will self destruct time and again.

Best to look for a modern amp module that can do the job.

well, looking at your link and the post with in, I would concentrate on the wiring of the input jacks.

Thanks for the thoughts guys. Got it all working ....so far so good. Someone at sometime had been inside there for likely a similar reason. However 4 resistors I noticed inside were incorrect values 2 of which were fried. Replaced all to match schematic and like I said so far so good...... It's now 4sale.........interested??
