Easy to talk about... not so easy to do in actual practice.

Wouldn't it be better or best to drive the amplifier with a
converted ham radio? Better performance all around...

Not in any case... you can't really get more than 310 watts
RMS clean output from the Pride DX-300. Both the power supply
and the tube will die a dirty death on the air... Blood from
a turnip doesn't happen.

Not worth it... not enough cooling to start off with.
