AndyH,
Allison - is the 5V at the collectors reasonable?? If so, is it time to replace R92 and R95 with pots and adjust until it works?
No.? NEarly all of the collectors from Q90 on are connected to the 12V bus (that is at 12V???) so unless the small
value resistors re cooked that is just plain wrong.? Check R84 (10 ohms), R89 (2.2ohms), r961 (2.2 ohms).
One end of each of those should 12v or higher and the other may be a few tenths less.
