The calculation seems correct, the voltage acoss the tubes filaments and the pilot s 28V (I am not sure what the pilot across the Candohm is but cold it gave me 6 Ohm that would make it 2V) sonI expected 27.2V which is close. Ultimately will measure current, it is the better criterion, should be 300 mA.
Update 10 minutes later....
I fully expected it to work, but nooooo....
No life in the speaker.
I looked at the B+.... 0V.
Cecked the 76 tube...dead. The filament is good, but the tube is fully dead otherwise.
I think, it is a broken wire - three of them have loose bases.
Anyways, Kirk - do you have a 76 toob?
