Moderator could fix it for you.
Greet idea, I am all for a SE project using my 2SJ28's. I have a sets of 2SJ28 and 2SK82 along with boards and brackets for another V-fet build, maybe, but then I was lucky enough to acquire an extra set of 2SJ28's with the hope of a new project one day. Circuitdiy sold out of them pretty quickly once NP introduced the V-fet project so there must be many more holding onto extra 2SJ28's like myself.

Aw geez, I meant 2SJ28's. That's embarrassing, now my thread has a very misleading title
In advanced edit mode is possible to rewrite this thread title

Ah, thank you. Just saw your post.
ideas to put them to use
Take IRFP140/240 as cascode devices and place them like this:
Then take any opamp and place it in front of that cascode.
Provide enough or even excessive current and enjoy.

Mended now
BesPau, you draw NJFETs, the guy has PJFET's. 2SJ's are PJFET's. 2SK's are N.
Oh, you are clearly right, sorry, i must check datasheet.
Than just pick IRFP9140/9240 and reverse polarity...
I'll post a couple of sketches to kick it off when I get in front of my computer.
Title changed! Thanks, Soundhappy.
Oops, it looks like the title changes, but not the actual thread title. Bad Mike
Oops is my bad sorry because is only first post title not thread title correction option
Question: Could autoformer connected gain stage like in M2 or similar with adaptations can play together with v-fet 2SJ28 DEF ?
Moderate price Edcors transformers or Jensens are cool irons.
Not classic Toshiba jfet's front end this time rater make them with small signal sit's 2SK79 ?
Mended now
Thank you, kind sir. Now we're off to the races.
