[AMPS] What (modern) tube to use?

The 3CX1200A7 (instant on, reasonable drive/gain, etc.) is certainly an
interesting tube but I'm concerned that the only commercial user seems
to be Ameritron and I have my doubts about the long term availability of
a tube designed for the amateur market that is not getting a lot of use.
The Ameritron amplifiers seem to have suffered from "marketing redesign"
according to user reports and the quality of the components used in the
plate circuit don't seem to be up to heavy duty operation (RTTY contesting,
etc.).
