I cant find a service manual of this amplifier, but I need to figure out what the bias setting of the amplifier needs to be.
The working channel has about a 1mv drop across the 0.1 ohm resistor, so i adjusted the rebuilt channel to match.
Seems to be working, but I would prefer to know precisely what it is supposed to be.

Gotcha. Will do. I also noticed these guys are getting old enough (1994 one here) that the SMD caps are starting to leak. So I had to go in and change all 25 of those.
The leakage was typically due to bad caps and didn't apply to all SMD caps. The DSM amps were the worst. Many other series with the same 10uF@16 caps are perfectly OK.
