Re: Vacume tube TC

Any tube will work. You just have to get it right. Keep trying.
Thanks for the suggestions. The tube is a tetrode and I have tried tying the
2nd grid to the 1st grid, to the plate directly, and to the plate with
resistors of various values: 100Ohm, 250k ohm and 300k ohm, all to no effect
(no brush output). Perhaps the values that I have tried are not in the right
ballpark... also how do I know if the 2nd grid current is "too high" (It
hasen't blown up yet).
Any other ideas?
