OK, I am tired and about to go home to bed, but this thought ran through my mind. Please tell me if I am overlooking something.
Say you had two plates with the same signal 180 degrees out of phase on them - like you would on a pair of triodes in a phase inverter. Would it be possible to drive a relatively high impedance transformer wired between those two plates? For want of a better term, I'd call it differentially driving. Or maybe it is more of a bridge.
Seems like as the plate voltage climbs on one side it is simultaneously sinking on the other, so ther would be a net small current flow through the winding passing back and forth with the signal. At zero signal the voltages would match, so ther would be zero flowing through this winding.
Perhaps it would require lowr resistance plate loads that usual and maybe higher current tubes. But that is details. Or is that the killer point?
it is not a matter of whether something else would do it better, I just wonder if it would work at all. And no, I don't know just what I would use it for.
