but unfortunately that URL only contains the first page of Broskie's treatise on the circlotron. I read the complete piece once upon a time, and I must say I could not/did not follow his argument about circlotron = totem pole (the Futterman topology). I would like to re-read it and try again.
Paul Speltz once made a case that is the exact opposite of what you state. His conclusion was that as power output from the circlotron increases, its output Z goes down. I printed out his post, possibly from the "Tweaks" secion of the old ASOG website, and I saved a hard copy, but I don't have an e-version to post here. I do recall that his analysis was based on his results in driving a signal backwards into the output of his own M60 amplifiers and observing how the signal could "push the output stage around" at different amplitudes. Maybe I can scan it and post it, or maybe Paul is out there somewhere.
But anyway, Tre' has not been making any claims as regards output Z. He is talking about Class A operation, or not.
