[Amps] Fw: "Tubes 201" - How Vacuum Tubes Really Work

[Will Matney]

Peter,

On that, I agree it's the only way to make one positive (for only part of a cycle). Are there any other ways to make the grid positive and the grid be at ground potential with the cathode at ground? A lot of amps cathodes are at ground potential unless biased.

Best,

Will
