I get that the power for the regulator comes from the B+, which is neat.
No need for a fixed bias traffo.I will run the articles past Bill and set his quote against the other plans I have for the system.
I'd add that I don't think the stability of bias or longer life benefit is a really big plus to me. EL84Ms are not expensive.Both LEAK St20 amps currently use 4 single Cathode Rs ie one per tube. Surely this makes a difference? yes? no?
More power might be a plus, though I have enough as it is.
