N-Set, this tube does look interesting, in that it mostly fits your stated theoretical desiderata, save the true triode part. It will also be interesting to see how you swing the drive voltage in only one stage, and how you will from there arrange an acceptable output impedance.
Like I keep saying, I have no idea how to tame self-effects with all the giant parts and high voltages/EMF in the same box. The scatter from an amp like this would light a grounded flourescent bulb at 30 paces, and the rails would support the MTA.
As you might have guessed already, I've been seriously zapped before, so this certainly enters into my thinking on this subject. This said, and more to the point here, I have no experience that suggests to me at this point that this approach would in the end bear better sonic fruit than a more conventional design.
AC heater, anyone?
