If you have any electronic surplus stores in your area, due check there. Always loads of capacitors. Military high grade.
Well, I got a 10u @100 volts and put it in and it seems to work but tubes seemed a little bright so checked the drop across them and got 82 instead of 68 volts. My line voltage measures 122 volts. Should I leave it or try another value cap?, if so, what value cap.?
