I have often thought of doing a 211 amp which
might run in class AB2, so CF drive is a good idea, and a high swing is
needed.
I would probably use a an EL84 in triode as the CF driver, Rout
200ohms,
so noise from stray C probably won't affect it much.
Yep, thats what this is:

Produces about 32w with a B+ of about 950v
