Often wrong but checking the filament voltage on the output tube really does not tell you if the tube filament is opening as your measuring across a set of parallel filament lines, not just that tube. Sorry. The big jump in voltage across that resistor could be important and indicates something has quit drawing power along that line. The one thing that draws a lot is the output tube. Try a new one!

Still nice to know if you observe the filaments of all those tubes going dead after the pop. I would guess not as you indicated the dial light stayed on.
