Bob,
I suggest you look at the schematics again. The output of the 5763 goes
no where near the modulator. I don't have the schematics in front of me but
I have done some extensive work in the audio section.

Mark,
Take a look at a Heathkit Apache schematic, (TX-1), for ideas.
There is NO driver transformer. The 5763 driver goes to the Mod transformer
and the EL-34s feed it for audio.
