With 15mA from each JFET providing 30mA through the 1k ohm = 30V. Only 15V left over on JFETs 😀

If you look better at the sch. you'll see two resistors (6k8 and 4k7) which divide the voltage between the PS rail and the ground and the middle point marked with 18V (and that's the Vds for JFETs). That's enough data to calculate the PS voltage even if you one didn't watch the video... 😉
 
Yes, it's very Curlian, and although I had not seen the Vendetta mc
stage previously, it's pretty obvious how one would do it.

In a less simple version the 1K resistors would be constant current sources,
and the supply voltage would be a lot lower. In this case though, we drop
30 volts across them for 30 mA current, and the 1K is a pretty large value
compared to the apparent impedance of the cascode's Source pin.

The standing voltage of the Jfets is about 15 volts or so, and they see peaks
of about 30V.

I recall that in the Blowtorch schematic that I did see that John was using
something like 200 ohms, but Jfets were not employed as the cascodes.

nice example of folded is Thagaard's RIAA (AXpress 01/2011), same as his 100W amp ( AXpress 10-11/2002)

don't forget wakoo A75 amp

Papa is folding (everything) longer than I'm wasting da air around ..... :clown:

(I can't forget puzzled ppl around me , several years ago , on the beach ........ they were thinking - "wtf is wrong with that Dodo?!" , while I was laughing , looking at A75 schm ......... )

It will?!? Wow! Ok... I suppose I should learn how to use Eagle or Gerber or something... That seems line it would be useful... 🙂 🙂 🙂

What I can do is Project Manage this circuit, and help see that there is a good PCB and support for this circuit. Assuming there is interest. 😎

😉😉😉
