SE-VFET is too obvious. So, maybe it works.

 

[Soundhappy]

We search the name for this one yes ?

 

[pinnocchio]

SIT-Down and enjoy the music! LOL

 

[soundslave]

How about "the baby SIT ear" or "the cyclops"

 

[Derekva]

At the risk of offending Honda, how about VMAX?

😀

I like Papa usual coded letter language about topology included in amplifier names examples :
C = common
X = transformer,
AX = autoformer etc.
CSX1 was common source with input Jensen transformer vfet amplifier
🙂

 

[Soundhappy]

Or the tribute name to the early days amplification pioneers
from Western Electric era who used triodes and autoformers
100 Amplifiers – Part 1 , 1916 – 45 | Lilienthal Engineering
100 Amplifiers, part 2 , 1945 – 54 | Lilienthal Engineering

Part 3 you say?

Revenge of the SIT
Die Hard with a VFET

 

[Soundhappy]

VSEA = Vfet Single-Ended amp with Autoformer
VAX = Vfet amp with Autoformer

Call it the SIT-2s for all the twos. Two jfets, two primaries, two secondaries and two output transistors. Keeping in mind the CCS could be a resistor or a mosfets that doesn't amplify.
More about the visual symmetry for me. 🙂

SIT-2-ation?

HI-FI+
SCI-FI = SIT-FI
the encestral engineers formula

We have "DIY Sony VFET" for the first DIY VFET amp.

How about "DIY Solo Sony VFET", or "DIY Sony Solo VFET", or "DIY Sony VFET Solo" for the single ended amp?

Look:

VFET Sony's Rare 2SK82 (KD-33) N-CH 1 piece | eBay

Although picture shows 2SJ28.

Update: I asked and they are 2SK82 KD33.

 

[Ben Mah]

There were 10 pieces, but all sold now.

Hopefully some DIYAudio members bought some.

 

[J2M]

Thanks for the heads up Ben. I have just bought 2 and had my order confirmed.

 

[WalterW]

Be careful, lots of fakes out there 🙁

 

[Dennis Hui]

Dang...wished I had known about it so I can snag a couple.
That is a listing from Acroman so I would have some confidence in it.
Hopefully those parts will make their way into amplifiers soon.

Cheers,
Dennis
