well, working on old amps that have been moth balled for years is frustrating...... checked C12 and the other lytics last night, all checked out. Now for something new.... -8v supply has been at -7.62v since day one...decided to poke around on the -8v supply section. I found that Q14 and Q15 responded to tapping...the screws that held them to the board were loose. Tightened the screws and negative rail went from -7.62v to -8.32v, none of this has anything to do with my original post but now the levels of the stray DC volts raised also. Q6 collector has gone up to +.428v (should be +.1v) and Q10 collector has gone to +1.45v (should be -.2v) I guess in the mean time I'll convert it to a 3 prong cord and see if it makes a difference, needs to be done anyway.
