F6 Amplifier

Of course they will be rare in a few days when everybody buys up the old stock hoping for a Pass F-something to put them in.

F7 may go commercial unlike F6. Who manufactures complementary SITs; SONY, Yamaha, etc to supply Passlabs? The SemiSouth patent also talked about SIT devices. wrenchone designed a circuit to L'Fake an N-channel SIT using N channel MOSFETs. His circuit can also make the complementary L'Fake SITs because the N-MOSFETs have P channel complements.
 
If I've understood correctly the magic of this amp is that the transformer splits the phase on the top and bottom .

What I wonder though is if it would be possible to invert one of the windings such that both parts would play in phase instead to try to get som single ended love?
 
Basically this:

Inverting one of the secondary windings on the transformer. Or will that result in no output?

This was the same as Mr. Pass schematic in post #1.
In post #292 Mr. Pass corrected the schematic.
Finally in post 306 Mr. Pass said, "Really, it was an honest mistake. The only mystery is how the circuit worked so well that way..."

So try it, it can't hurt anything! Easy to switch back and forth.
