Hey Dave

I'll try that over the weekend and see how that works out. Hopefuly that may clear up or at least partially fix the problem. I could see if some of the condensers have high leakage or are shorted it could be messing up the voltages. I guess I'd be looking in the wrong places if I just started popping tubes.

On a side note, I have heard of tubes lasting for decades while the condensers go bad. Yet I have a big box full of electrolytic condensers from the 50's-60's, which I have been collecting over the years. Most of the values are dead-on when I test them with my meter and have been using them in small projects with no problems. Did I just get lucky with these? Or maybe they just haven't failed yet?
