Is VFet an internet influencer thing that makes no sense at all?

[Stuey]

I believe some are conflating VFET (SIT) with vertical MOSFET, or VMOS.

Indeed, my bad.

Got another vfet amp!
1 of 1 in the world
Sound vs other vfet amps difference is very subtle.
smooth and comfort.

the front end triode would bring in its own sound

No no, I just forgot to post it after arival. I am listening to it all these days.

You need to have your amps properly restored so you can actually listen to the way they supposed to sound, otherwise you are just experiencing an old amp with nearly 50 years of aging on its last leg....

I will guarantee you that if you like how some of these amps sound now, you would be blown away after a proper restoration. but CAUTION...(if this wasn't mentioned already): one could make a nearly 50 years old amp sound worse by replacing aged components with wrong components. Unfortunately, older designs are very sensitive to replacement components.

But is it possible to mimic a V-fet? ... YES ... How?

Any updates to this? Maybe something like this?

Not according to your #52, nor #53 with smoke warning.
And pretty much everything else I've seen.
Further references in #114.
I've posted a picture about this on diy a while ago, but I don't remember where...
Oh, here it is!
Elaborated on it, and a spice-sim analysis.
Suitable for J/mosfets & bjt's indifferently, three E6 range R's are sufficient to do the job.
Temperature stable, the bjt-bjt combo as well (no run off).
Not found a publisher yet, alas. ("Is it arduino?" "No, fundamentally!" "Good luck." 🙁)
