on how much RF power an 01 can handle? Can it drive
a 45 power stage?

I have various old tube manuals in print and on disk.
None of them seem to list the maximum ratings for the 01A.
Maximum plate voltage seems to be 135 volts and max plate current
seems to be 3-5 ma. No mention of plate dissipation, but I think
that the plate voltage/current limitations will be the factor
here. I think the type '171 ('71A) which was used as an output stage in
old radios would make a better tube for this purpose. It can handle
up to 180 volts and at least 20ma of plate current. Again no plate
dissipation rating given. Also consider the type 12A, which is
a 'heavier' 01A rated to 180 volts and maybe 10ma of plate current.
