Hoffman 610 Lost B+

Well, from what you gave us, either you are not getting the current needed to drive the set....
So check out the 3 windings on the B+ that feeds the 5U4, check out the 5U4, are the
lights on..? Like O-C said, check the resistance on the transformer with the set off and
unplugged. CT also.

Other option, you got a short, or over driving that audio output tube..... is the 470K
resistor ok r112. Is that tube looking a little hot....? Audio output transformer a little hot...?

I'm thinking O-C is got a good idea in looking at the transformer, at least go there
first, look at the 5U4 too...
