"My first recommendation would be to only consider older vacuum tube
or hybrid gear (solid state receiver, tubes in part of the
transmitter) if you have experience working with vacuum tube
transmitters.  It is too easy to destroy hard to get transmitting
tubes while you learn".

One of the most common PA line ups of hybrid transmitters is a 12BY7A
driver and a pair of 6146 finals. Without searching hard, you can get
all 3 NOS at a fester for $12;  less if you put some effort into it.
