Very exciting design 🙂
Is the feedback compensating for the transformer distortion? I mean like this:

I've just hoped to get news from Nelson about SITs.
Neslon, is there any chance that we will see a SIT-F6? What about the availability of SITs?
You can build this circuit with just about anything, and that is the point of
such a topology. The Jfets I used are nice parts, but not the central thing.
The central thing to me was a nice passive way of isolating and splitting the
drive for the devices while at the same time implementing feedback, all done
passively by the transformer.
Sits will work fine, as will ordinary Mosfets.

A SIT or depletion mode device I would think would need some alterations to run negative voltage to the gate.
Come on now I can't keep up! F5, L'AMP, F6! I should just buy shares in Plitron/Digikey. 🙄
P.S. Many thanks to Nelson for his generous support of the DIY community!
why you guys keep addressing NP directly,for tiniest issue , after all this years ?
what's wrong with your own brain ?
I know you have it !
but prob is that you're not believing that you have it .

Fortunately Mighty ZM answers the little questions, so that I can concentrate
on the big stuff...

well
I'm here to serve and protect ............
and to mislead
(every fool have it's own burden )
OK, mister answer the small stuff. (No misleading allowed!)
Do the output devised need to be matched? If so how close?
I don't know for sure, I listened to Nelson on the recorded presentation and I though he said something about mismatch would be equalled out(?), but I am not sure how that affects distortion or if that is what he meant.
It is hard to skim through a presentation.
The devises I am looking at are rather expensive and sure would be nice to know what to order.

Thanks to Tea-Bag, I just received 2 pairs of Vgs matched R100A for my wife to wrap as a X-MAs present. She looked at me and the R100As surprised; this much money for these; said she? I was tempted to tell about the potential price of a Pass SIT; but kept the peace.
