Actually this is a tube rectifier on this circuit. It is a 330uf cap I believe and I do think that this helps the amp kick like it does. It has way more punch than I originally thought it would. I don't think it would stress anything. The 5Z4 is an indirectly heated cathode. I looked this up in the RCA manual and it is similar to a 5Y3GT. It warms up slower than a filament, so that may help avoid surge. I did connect the green/yellow transformer wire to ground. It may be like you said, Brenda, a shield. I left the line caps in. I didn't think they would hurt anything. I get a lot of noise in our power supply out here. We are at the end of a line. Yea, I live in the middle of nowhere
