Thanks, that makes sense and thanks for the numbers. As soon as I replace the filter caps I'll see how it sounds and go from there. Then those numbers you listed might come in very handy. Even if everything sounds good I'd like to get schematics of the boards anyway as I plan to keep and use the amp a long time. I've found it's always good to have the technical info for something you can work on! I'll get to that asap. My wife just had a baby a week ago, so things are still a little hectic around here and I haven't had time for the amp, needless to say. But I will in the next few days.
