So far all commercial applications I've found are as
modulators,
not RF tubes. They are supposedly usable to 30 MHz but
have
yet to find a real world RF application other than the amp
I have.
I'll trace out the wiring and come up with a schematic.
Once thats
done I'll be able to figure out how its biased.

Lots of snipping...

833A's were widely used in AM broadcast transmitters
both as finals and modulators of about 500W to 1KW rigs (RCA
BT-1 etc.) and as drivers in higher power transmitters. I've
seen designs for ham transmitters using them but I don't
know if any commercially made _ham_ transmitters did.
