Dual 45 tubes in a Philco 20?
#3

Kirk
  I think that someone just grabbed some random four pin tubes and stuffed them into any empty socket, it would not surprise me if they were duds to boot. The #71As should be side by side near the middle near the rear apron, and the #80 should be in the rear corner next to the block condenser can. Nope, #45s don't belong in there, the filaments may not burn out straight away but that 5 volts will wear them out fast.
Regards
Arran
