[Amps] GU81-M on highbands

[DAVE WHITE]

Hi Tom - Somewhere I have a circuit from a Hungarian amateur that uses a single GU81M on 80-15m.  I'll try to find it (a major operation in my library, and not one guaranteed of success!!) and scan it for you if you need it.

cheers

Has anybody used a single or a pair of GU81-M on highbands? Of course I see the
problems with the high output capacitance, but there can be solutions like
L-tuning or a small L before between tube an plate-capacitor.

Has anybody done that in practice?
