F5 power amplifier

Patrick might be able to help Audioholik with his voltage question. I believe his F5 is running 16V rails.?.
Of course he is running his own balanced version but might have some good input.
Also, looks like Fredlock is getting 22V rails http://www.diyaudio.com/forums/showthread.php?postid=1565412#post1565412
And I went back but didnt see any Zen schematics. Must have been in the B1 thread.

Attached is what I deem to be corrections regarding the fets that where pointed out. Maybe someone could just double check...

Yeah, I saw they regulated supply that is touted in the F5 document that makes the rounds, and that is a dealbreaker... dropping 8V... 8x amount of amps = alot of heat very quickly... almost half as much dissipation as the amp itself...

Then I remembered the picture I saw on 6moons

Now if only someone could reverse engineer that one, as Nelson seems very secretive about it...
