>>SO it's ok from the power transformer,to the voice coil, but then gets lost somewhere between the voice coil and the output transformer.
You meant the field coil, right?
In addition to the above: simply check the panel of the 42 tube (without the tube installed and un-powered), which had the lowest voltage on the pin 2, buzzing pins 2 and 3 to GND. Especially 2.
Note the resistance.
if nothing conspicuous, repeat for the other 42 tube.
