I've been very interested in the VFET threads and NPs SITs. At Burning Amp, the SITs were the talk of the event, literally.
So, I was thinking, if one were able to acquire a pair of N-Channel VFETs or SITs, what would you build?
A circlotron seems an interesting answer, but the designs I'm aware of take two transistors per channel, so the circlotron is out - the challenge is for a pair of outputs. One can use other FETs to bias, but only two VFET/SITs to design with.

Something with a CCS load in the output stage, Zen V4, J2, F2, Aleph M.
Or a single device design, BOZ, http://www.diyaudio.com/forums/pass-labs/66822-sewa-seven-watt-amplifier.html

You need to contact Mike Rothacher on these forums. He already has things cooking with the Sony VFETs.
Don't need unobtainable devices, just Darlington or Sziklai arrangement of
Triode and BJT. Mu senses collector voltage of BJT, and the loop is closed.

Actually, the Sony part is a drop in for the IXYS part in the Delite amp. Just a few resistor value changes and supply voltage changes.
Was a video made at Burning Amp?
If only 2 N-channel SIT per channel, I would make a quasi-complementary ouput!

Greetings! This thread interests me; Minimum output devices, Zen-like circuit, Silicon carbide...count me in.

See SIC with mosfet CCS. Post #764.

I'm running R085s in a Nemesis style (1:1 XFMRs) as my main amps now. Hard to find fault with!
