Greetings,
Thanks Rich, for the explanation and idea. I have a 3300V xfmr which should
give about 4600V. If I did want to use this thing for RTTY (which is unlikely)
I wonder about this idea: Make the power supply switchable. That is switchable
between choke (nonresonant) and cap input. The only problem I see then would
be that the tank circult becomes a bit more complicated.... that big of a
voltage difference would surely require significantly different L values, no?
Ideas?

** True enough, however, by increasing an AB1 stage's anode supply V by
the amount of the screen-V (800V in this case), the anode-screen V will
be the same as in AB2 cathode-driven/grounded-grid, so the output in AB1
will be quite similar to that in AB2. Thus, the output from a g-g/AB2
config operating at 4000V will be c. the same as grid-driven AB1 config
operating at 4800V. For 4-400As in AB1/SSB, 4800V is do-able. For AØ
or RTTY, forgetaboutit.
