Without a doubt; whenever I see the word "revelations" I know to duck. Actually I sort of thought he might be a total crank but I am not knowledgable to discern this. I really don't care about his philosophy I just thought the amp was interesting so I posted in the hopes someone such as yourself would offer a comment. It is interesting reading though unless he talks too much old hat there of which I wouldn't know or be aware. Thanks for providing the checks and balances. Oh; and BTW that is a balanced input, right? See there is a guy out there who is building PP pentode amps with Tuner tube drivers and damper diode PS filters. I thought maybe that is the circuit he copies.
