I still have several paper caps to replace and check resistors and tubes, so theres a lot of possibilities. ALSO, I forgot that I still had two sections of an old electrolytic in use. One is a power supply filter and the other is an output decoupling capacitor.
I strongly suggest that you replace all of the remaining paper capacitors before applying power again. By not doing so you are risking damage to more expensive parts. Leaky paper capacitors (and by now most/all of them are leaky) cause excessive current flow which will burn out tubes, transformers, deflection yokes, etc.
