I have an extra 811 and socket and was wondering if there is a way to
use this to plate modulate my 811 cw transmitter.

Reminds me of a phono oscillator I built as a teenager out of old TV and
radio parts. Had a 6F6G oscillator modulated by another 6F6 coupled by
an old TV filter choke. The oscillator coil was wound around a
cardboard tube from a roll of toilet paper. With 300 volts on the
plate, It had a range of a few city blocks.
