Looks like one more argument for the thesis that caps ssuck!
Sorry for a naphtalene-smelling idea, but how about VR tubes *here*?
It's an light-weight MF channel.
The current variation VR's will see should be very small so perhaps
charge redistribution time-lags become unimportant?
Would/could you share your friend's views on the last cap operation
(separate thread perhaps)? Thanks!

The subject of the gas tubes driving the single-stage amps was well contemplated in past. Unfortunately the gas regulators available only up to 150V and only up to 35mA (25mA practically). There are some higher voltage gas tubes (1000V) that are hardly useable and there is no knowing to me VR tube that would care more current. It is not to mention that VR is very slow sounding regulator and I do not particularly feel that it always a good solution to drive anode.
