Anyone really, really old dudes on hear who can advise
on how much RF power an 01 can handle? Can it drive
a 45 power stage?

No. I don't have technical references as Ken does, but from
practical experience (hope I'm not disclosing my age here),
but the 01A is much better suited as a receiver RF stage, or
a one tube "regenerative" set.......... or maybe an audio amp
driving headphones.

If you're bound and determined to use these old bottles, a
better choice (I think) would be a 45 oscillator driving another
45 amplifier stage.

I've tried using 01A's in transmitter duty, but usually ended up
noticing a bright flash and then no more glow at all!....SOB

A 45 by itself as a one tube, crystal controlled transmitter isn't
too bad either. An FCC monitoring station somewhere in
Nebraska (If I recall correctly) objected to my 45's key clicks,
however. (And I was running an honest 3 watts on 40 in
Washington State.
