Ok next step would be measure the resistance from pin 1 to chassis and then pin 4 to the chassis at the 80 socket. Both should show high resistance like 7000 ohms or higher.
If that is ok then measure the resistance across pins 1 and 4 (the two fat ones) on the 80 tube's base (again not installed). Should see a very low resistance just a few ohms. If it's open (no resistance) the tube will need to be replaced as the filament is broken. With a dead tube you can carefully bust the glass off of it and unsolder the wires from the pins. This can be used for a spkr plug or a tube adapter at a later date.

figure out what all those squiggly meant.
