In Reply to: RE: Quick question: How do you filament bias a tube that does not have a filament? posted by Nickel Core on October 16, 2014 at 10:50:52:
It simply isn't filament bias, but rather a fixed bias supply.
If you have capacitors in the DC supply feeding the tube/resistor, then you haven't exactly accomplished your goal of not having a cathode bypass cap.
This is sort of like saying that you have a regulated screen grid on a triode. A triode doesn't have a screen grid, just as an indirectly heated tube has no filament.
(Your plate voltage shouldn't be that far off IMO by-the-way)
