Marty, important to understand if all the filaments go out after the "pop". The rectifier (an 80) is the exception, it has its own supply for the filaments. I hope you examined carefully the two wires that jump from tube to tube and carry the filament voltage. Poke them a little and maybe reheat each connection. It certainly is possible you have a tube with a filament that opens up when hot but that would only kill that tube.

Quick not to Marty, why didn't we think of this before? The radio has a dial lamp, does it work prior to the "pop" and does it go out post pop? Examine the wires going to it, they have been known to deteriorate badly and the case of your radio, neither wire goes to ground.
