I am thinking of building up a single ended 4-400A for six. Mainly cuz I've
got a old homebrew HF amp with a good bit of the "stuff" I need to do it
with.

I wonder (since I'm a bit rusty these days), if I can Grid Drive it? I will
only have a basic transverter output (8Watts) available.

Anyone point me to a site or material about the input and output circuitry
needed?

Any thoughts?
