I'm working on a 1060 amp with one distorted channel.
The good channel has appx 30volts on H004 emitter, the distorted channel has appx 11.5 volts on H001 emitter.
Have replaced H001 and 002. Replaced all other semis on that channel, even though they tested OK. Replaced all electrolytics on that channel, all other films and ceramics test OK.
R723 is good. Shows no abnormal DC resistance on J709.
Any ideas on what is drawing the voltage on this channel down?
