"that output had the filament current fed from a high impedance source running through a tertiary winding on the OT to offset ~95% of the anode DC so a minimal gap could be used. Kinda like what happens in PP but with a single tube."
That's a really good idea. I've thought about something similar using a simple resistor to offset the current, but that really kills efficiency. When all is said and done, I think Class A push-pull leads to a better solution. Many EL84 PP amplifiers operate very near class A, which might be one reason they sound so good. The use of triodes should make this mode even better.
