Well the 'shocking' joke was in reference to the capacitors in Tube amps can zap you, even when powered down/unplugged. One of the output channels on my receiver/tube amp isn't working and I wonder if it's worth poking around (with my limited electrical knowledge), take it to a professional, or sell as-is.
Since i hold most of the Marble Connection members in high regard, figured if one of them was also a member (or knew of) a good vintage audio forum it would save me some trial and error. Kind of like if I were a member on a car forum (or whatever) and somebody asked me about a good marble site I'd send them here
