any possible small octal or 9 pin tubes that can be // could work with 0v grid bias and / or UL output connection??

thinking:

high current buffer input then to a 1:20 step-up to a 0v grid bias output stage.

looking at 6v6 etc...

possible 20W output or so. low power supply v and high current.

any ideas?
