Yes Marty, I did note that center tap to ground but if was intermittent your filament voltage would have doubled! Not a problem there. I did have a problem on the center tapped type of filament drive on a light bulb with a short to ground, caused wire to smoke. Not a pretty picture until I figured out what was going on.
Probably time to hook a meter to the filament feed and see if it drops off when the radio dies. If not, you have a tube problem with either a dirty connection to the socket or an opening filament.

PS: Marty, when it dies try the little finger touch to the volume pot, if you get the happy hum, you will know the problem is not in the last two tubes.
