Thanks for suggestion. I have some 2E22s, even some 2E24s
(quick.heating versions).

The problem with the 2E22 is that the output power would be small
(probably 10W or so) because, using suppressor screen modulation, the
efficiency is rather low (30%).

Using two 803s I can instead get 200W or perhaps 250W of carrier.

Hi Tony,

The 2E22 is a true pentode while the 2E24 is a quick heating filament
version of the 2E26. Both are beam power tetrodes and not suitable for
suppressor modulation. A pair of suppressor modulated 803's will deliver
approximately 100 watts of carrier.
