From my Techs notes
"Replaced timing capacitor, c604 in protection circuit and cleaned the back of the protection board from corrosion.
I cleaned up some of that corrosive glue as well.
Tested at 96 W
DC offset is 0.0mV in both channels and the bias is at 20mV in both channels. It is loud.
Somebody did some work on this before replacing a capacitor on the protection circuit. The rest were tested while I had the board out and all appeared to be within spec.
In the future, someone will have to redo the amp boards, like with all vintage stuff. I cleaned the corrosion off the back of those as well, Its running great and bothering my family. Probably my neighbours too."
this is a super clean amp with rare rack handles and Original box!!
