[Tank]

Thank you all for the advice. I figured out what was wrong with my A battery pack. Very stupid mistake; I accidently had two of the batteries in series. Wiring under chassis is good, no shorts or corrosion. Resistors seem to check out. Will be checking resistances on all tubes next. Did have one tube that must have been broken when I bought it.. With luck I will just have to replace a General Electric tube marked 8-48 118-5. The connector on top of the tube was loose enough that it had fallen off. Any suggestions as to where I could purchase a replacement tube?

Thanks again.
