JFET and ZEN
 
Anybody tried to cascode the MOSFET in the ZEN amp?

Something like the Power JFET amplifiet, this will reduce the miller C, but perhaps the main problem i Ciss?

It works fine, and that was the original ciruit for the F3 last
year. I still have it laying around, the performance is not
as good as the JFET, but it's still better than the Zens.
