FYI: THe 2E26 is a good small rugged tube. It was used as final in
the Spy Sets used by the clandestine community in the cold war days.
I have one of the sets, and it will literally tune into anything and
work off almost any power source. It is crystal controlled, but I
don't have any schematic.

One of the older ARRL workbooks will have lots of circuits for the
2E26 tube, circa 1950-1960.

I want to homebrew a crystal controlled (or VXO) CW Tx, (capable of break-in
operation) that employs a 2E26 tube in the PA. With ICAS operation I can get
27 watts of RF out with a driving power of 0.17 wattts (according to my RCA
sheet). I want most of my "design" efforts and interest to centre around
the PA stage. I think I could cope with that at least.

Can anyone please point me to a suitable solid-state exciter circuit? I want
the Tx to cover any HF band (I'll use plug-in coils). TIA.
