[Amps] Grid vs cathode driven

10 of them can be ran grid driven? The Galaxy amateur amp was a good example
of this. I have built them using as high as 10 in G-G in parallel. No neutralization
was necessary, and they ran just fine. I've used as high as 4 grid driven, they did
ok too. I'd try this first before do that arrangement.<
Quite. I was merely trying to make the point that tubes that ran high current at low voltage gave a better chance of getting a useable wideband xfmr.

I don't like sweep tubes anyway.
