Best comment so far this year. ... 😀“If it ain’t oil, the sound will surely spoil”
(Said nobody, ever)
I can't decide if I'm being lazy or magnanimous. Since I have one DIY VFET amp, I'll let others have a go.
Generally, n+1 is the right number of amps to have, where n is the number of amps one has. 🙂
In any case thanks everyone for all you share.

Did I miss the offering? I was checking back throughout the day but didn't see it pop up in the store.
Has not happened yet - also there will be 180 kits in total. 90 using P channel Vfets and 90 using N channel Vfets, as per Nelson's post.
I participated in the Pfizer trial this summer, but got placebo. Now 10 days after my second real vaccine dosing. (I’m a physician) They are currently vaccinating 75+ in my state. I think the healthy, younger folks will end up getting their shots at drive though locations after more of the vaccines are approved.
That being said, the COVID “break” allowed me to finish off, and refine my M2x monoblocks,and work on way too many daughter cards.
Looking forward to this new amp 😎
Don't despair, this amplifier will have a LOT of life in it, and the vast majority of the (at least 10) configurations of this project will not be reliant on unobtanium. 😀
It's going to be incredible.
Excited about the release, I am new to VFETs as I am a tubehead but have had my eye on trying one of NP's VFET designs. Assuming I'm not lucky enough to get one of the 180 available kits, is there a particular VFET that would be recommended as an alternative that isn't completely unobtainium? Seems the 2SK180 and 2SK182 are available. Apologies if that is a stupid suggestion, unsure of the particulars of the circuitry.
Thanks Jim, I do also hope the great looking chassis you posted a pic of will also be available as a stand alone item to buy - especially, if as you mention above, there could be at least 10 configurations to build. Members around here will be busy in 2021 with this multi config build VFET amp and the new Stasis design - all due to the great generosity of Mr Nelson Pass. 😀
agree with constant "n", but in my case, additional figure is always 3+n, which is exactly how much I'm behind schedule
re-read this (in case of Tokin SITs I believe some value changes should be needed but applicable; they're N channel, so accent on bold):
There will be two main releases. First release, any minute now, is 90 amplifiers using
the P channel VFET. This release is complete kits including chassis, far as I know.
Second release, much the same except differences to accommodate N channel
devices. Same quantity.
Additional releases for those with TO-3 VFETs of their own - 2SJ28, 2SK82
and 2SJ18, 2SK60 and anything else similar. These partial kits will also accept
various TO-3 FETs with the same pinout arrangement.
Also planned are pcb's supporting TO-247 package parts with store's UMS
mounting pattern.
just done I have 2 x 2SJ38 (Yamaha).
Would they be sufficient for a low power version of the P channel VFET option?
Assuming that the current source is a regular Mosfet.

COOOOOOL SE Vfet is coming 'soon'! But it would be unfortunate if the case is included... certainly for EU-people (and probably other continents too)... its going to cost us on shipping and import costs + VAT (while I believe the case is originating from Modushop in Italy?). Hope the case can be chosen as an option.
Do you feel lucky, pun*? 😀 😀
With hundredths of those with their finger on the trigger, one should be very lucky to get a kit.
But, there is a hope. Raffle was mentioned but not confirmed.

Perhaps they will use a "wizard" in the ordering process. Take a look at how they treat the ACA in the DIYAudioStore - a nice, orderly, wizard lets you pick and choose the various options.
