the cold solder join theory is becoming stronger.
If there is a bad joint, and the current for filaments is quite large, and it heats up due to a higher resistance and stops conducting....
Just go and wiggle your filament wires, and if all of the filaments go - look no further than where the transformer connects to the very first load.
PS> Just a guess but if that's the case and the radio goes "pop" and then goes out, if you leave it like that for a while it will probably will go back on again. And so it will cycle.
But it may not be a very good thing to do......potentially.
