voltage on tube heater 46-350
#5

Resistors can be used to counter high line voltages, but either a bucking transformer or Variac mounted separately is a more efficient idea. Neither of them produces the heat as a resistor in the job would.

Any AC voltmeter with appropriate range can be used as an output meter, as you are just reading audio levels on the output, after using a tone modulated signal generator to accomplish set alignment.
