I see two basic designs, both N channel, both single ended class A,
one Common Source, one Common Drain, all scalable to accommodate a range of parts..
Thanks you again Mr. Pass

Wait and see if they are hockey puck IXYS ?
Meantime genuine last ~ 100 pcs. still in stock from two good sources.

Grab Diyers some power triodes pair if you can..
..before all is depleted and being too late
Do they think we are dumb?.
No, they just understand how diyers function.
The vast majority of these parts will SIT for years in drawers before going to the Swap Meet 😛
@ Analog_sa
You can find sometimes Sony Vfet's or Tokin's in the swap meet but is low around ~ 5%
of all Diyers stock if compared to 95% build amplifiers from different articles or lottery kit's.

yes hoarders and greeedy boys abound. I once worked in Cghina, spent weekends loitering the electroncs markets.
You know, there the local prices there are high : f.e. 100nF Jensen caps, desoldered or just cut off a PCB, 10 USD ea..
Sometimes found something special - so have a bag of 2SK176 and 2SJ56, well matched in pairs of 4, used for my F5. Some 30 are still just lying there . . .
You should see my boxes.

You have to wonder how many are purchased with the thought of resale when the supply goes away, too.
well, that is a very risky thought, investing in goods on a long term market, while there is no garantee the parts are real, not 'certified' etc.
Speculation does not work when there is no real market.

In the past Sony Vfet's was easily available.. actually we didn't see genuine parts available from the reselers,
but fake transistors sellers on eBay and AliExpress ex: Polida etc.
Attention

For example old Toshiba have this very dark blue ~ black color around the pins like strange ""Tokin"" from Dalbani

Thanks Pras1170 for your new shop link! Congratulations +
That's funny, last day in the morning I remembered my dream and it's not happening frequently.
I haven seen images of many huge amplifiers with big Tokin's made by Diyers in the future,
they were highly appreciated despite hard work involved.
Some of them have a relatively simple topology, the other ones were more complex
and both amplifier types have his own favorites aficionados..
Hahaha was a such nice dream 😀 Best regards
@ WBS and Diyers
