Yup, I believe what I said. I built a "flywheel" supply, tested it, and posted scope photos. It worked exactly as the simulations predicted and reduced the DC output impedance by 50%.
I may not have time to write a book-length thesis to defend what I said above, but I stand by it. The laws of physics are mostly immutable, but the application of these laws is non-trivial. I can't take anyone seriously who says the laws of physics "prove" this type of power supply can't work well. There are good physical and practical arguments against your position.
Please don't assume I'm defending Jeff and Dennis in general. I think these guys couldn't reason their way out of a paper bag. My argument cuts both ways.
But seriously, your self-righteous indignation doesn't seem supportable by facts. It's also unproductive and embarrassing to people like me who are trying to establish some credibility for the technical side of the debate. People build amplifiers with these supplies and they work fine for them. You should put your effort into finding out why.
Besides, 50uF is more capacitance than most classic tube designs ever used.
