Or could it bee the "COMPACT" ...

off of Ned's site?
http://www.triodeel.com/compact.htmland then look at the work/mods by Yeo at
http://diyparadise.com/simpleel84.html
what strikes me as utterly elegant about this cicuit is it's simplicity....
low parts count... singe ended voltage amp up front....
a friend of mine was showing me a McIntosh 240 amp schematic where they used the same "long tail" phase inversion (but not in output stage)...
looks like the big trick is tying down the cathode sufficiently...
and of course you could go wild and do parafeed PP output stage to get the benefits of much improved PSRR and etc....
but I think conceptually it's a competitor to the very fine work of both allen and Lynn.
