I was playing this last night, unplugged it for a few min, plugged it back in....no audio. Checked all the tubes, all light and test good. Very small amount of hum from speaker. So looking at it tonight, found what appears to be ecaps in it. Big black box ful of tar. Problem is the drawing in my riders book show no value or polarity
Why are these old diagrams so vague???
Anyhow how do I figure out polarity and value?? Nothing on box, some writing on the bottom(see pic)
