• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

I really, really wish I hadn't done that...

And HF compensation in pwr-amplifiers (toob of course). Might get a nice shock tho if it were connected to some voltage!
And back to the 5 tube radio; it would most definitely be a "12" not a "6" volt filament. Duh! 300mA vers 150mA, the other tubes would geeit too much "juice" and shine nice and bright while the 6AV6 would barely glow. Now they add up to 121V, close enough.
If I'd been on Jeapordy I would've missed the answer or question however it goes!
Good catch guys! ;) Must of been all those 6A^6's I was looking at in my tube stash. Got dozens of 'em. A 12/6AT6 is 1/2 of a 5751.
