Gary (et al),
How about adding a tertiary winding to the step-up transformer, and use
that for the out-of-phase neutralizing signal? One end of the winding to
ground, the other end to a neut. capacitor connected to the plate?
You may be right on the requirements of the drive signal to the swamped
grid. I have a couple of ideas there.
