It’s one I got on eBay shipped from China, and I got a vfet nameplate made by a trophy shop.
I have a 2nd one of these chassis for a project that will come to life later this summer…

It is an Artemis Single Rail supply.
See this link, and email is on the page. Just drop an email to Gareth and he can set you up. Shipping is from UK.

It's a CRCRC + Regulator. In my case I went with a 20V regulator digikey p/n 2129-NJM7820FA-ND

Update. I put a Slagle AVC in after the 2SK79 B1 buffer. It sounds fantastic!!!
If I ever do another AVC it will be the pre-wired version. It costs more and requires a taller chassis, but this wiring (and rewiring - long story) took a good bit of time.
This is a 28 step autoformer with a 24 position gold point switch. I ended up taking a linestage with gain and a stepped attenuator to figure out which taps to use on AVC. Worked like a champ.
Ende gut, alles gut!

One of your posts about this inspired me to try it.
This one is a keeper! I put the top back on last night, this one is done. Superb sound quality!
Sorry to dredge up an old thread, but I just discovered this and it looks like an incredible project.
I am going to propose maybe a slightly risky idea. Do you think the 2SK79s could work in a Mezmerize kind of circuit, with both positive and negative power voltages applied to cancel DC offset? Then we could do away with those 'fancy' caps entirely....
I hope one of our VFET veterans can chime in. I don't know much about these devices, and I certainly don't want to buy a set and burn them up!

I’ve not tried it, but I’m sure it could be attempted successfully. I just stuck with the B1 rev1 schematic because of the simple supply, and I didn’t mind a decent film cap in the single path. Ultimately, my favorite spot for the K79 has been in the basic SRPP circuit that’s a few pages back.
dont worry about sound good too ,I haved all no caps in series from phono to speaker ..Now I learning from Nelson that sound really good too, he use like a donut , my last two amps have 10Kuf gofigure!
Hi Cody!
I tryed to draw a 2SK79 B1 board according to your schematics minus thermistor.
It is a concept experiment.
I made parts silkscreen to look like in original B1 and tryed to mimic B1 layout with hopes it emanate Papa vibes. ))
It went at least interesting..
