Sorry about some of the details. X = Vds (V), Y = Ids (A).
flg, in post #47, Dr Mazzola has a way [in upcoming article] which enables a SemiSouth JFET to behave like a SIT. Zen Mod has promising results using Schade Feedback as he said in post #50. Dr. Mazzola may wish to early release a schematic of this hot topic.

Hey ZM, maybe you could explain what's the difference between my "supersymetry" pre idea and "Ultrasymetry".
You better not tell me to go read the XS lit!
A picture is worth a thousand words
I can go home and find an X-600 pic that looks like my "Supersymetry"
