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

[Will Matney]

Marv,

You just hit on the book I stated reading today, again for the umpteenth time. There's so much in there, it's hard to remember it all. You are correct, it's surely a book he should have researched. I figured I'd give myself a good read today since there's not much on TV on Sundays.

Best,

Will
