I am looking for recommendations on the best all-tube 80-10 SSB/CW
transceiver to buy.

I would prefer:that it be smaller rather than larger, and that it have
a built-in power supply. I realize that this is likely to be a
contradiction, so I'd prefer the built-in power supply over the small
size as this is going to be set up in a portable installation
(motorhome) and the fewer separate boxes I need to mess with, the
better..

The only absolute requirement is that it be all tubes, no
transistorized VFOs or any such thing, although solid state rectifiers
in the power supply are OK.

Thanks...
