The only thing that connects the two pins directly is a small mica, which I robbed out of a parts chassis to no effect. I've done the obvious resistor and cap checks in the vicinity.

Forget your "golden screwdriver treatment" for the moment, you have a circuit wired wrong.
Pin 3 is a filament.
If rest of the set is working, that means the other tube's string filaments are lighting.
Unplug the set and ohm out the filaments in this area.
Pin three should have a choke and not a cap!
