I guess within one kit, the 2SK82 and 2SJ28 will be sequentially picked? So then with 2 kits you will be good to go. One kit for the left channel and one kit for the right channel.
I would like to go for your original dual pair VFET sony p2 design . Therefore, I ordered 2 kits because I thought that way the VFETs are suitable for this application (your post #1271
http://www.diyaudio.com/forums/pass-labs/276711-sony-vfet-amplifier-part-2-a-128.html#post4746425 ) , but maybe I misunderstood it.
Anyhow , I am sure the DIY P2 version is as nice as the dual pair p2, however, having more power and the additional options in the dual pair design are very tempting ;-) !
Thanks again for all your efforts and supports giving the chance to your community to enjoy such unique amps!
best wishes
Thanks for your reply. That would be very nice if this is the case. I hope Mr Pass or Variac can confirm/comment that.

Single-ended Sony vfet amplifiers new chapter in Mr Pass book writing ?
Yes please Papa
In other words you are treating each kit as having 2 pair (for two channels).
Since within a "kit of 2 pair" picked sequentially they ought to be reasonably
matched, I don't see an issue, as there is no requirement for matching
between channels using 2 pair.
If you are still concerned, wait until you get them and report the numbers
marked on the devices, and we will see what needs to be done - probably
nothing.

i`d love to have a little Vfet-SE amp for my kitchenradio : )
i guess a lot of guys (like me) were able to buy just the 2sk82 due to the non-availaility of the other vfet.
however, no urge, just good news about the possibility 🙂

I would think it's the other way around, first the 2SK82 was sold out and since a few weeks the 2SJ28 is sold out at Circuitdiy.
Is it possible to use 2SJ77 and 2SK213 instead of the 2SJ313/2SK2013 combination? pinout differences taken into account!
I would like to see the P channel using the 2SJ28's. I bought a pair of them just for a this last year when you mentioned maybe designing an amplifier around just a common pair. I am not sure what CD means, excuse my ignorance, but I think I would like to see a CS (constant current source). Whichever you think is best would be great for me.
Thanks to Mr Nelson Pass for all he gave to the DIY community worldwide.
I really think that this project is more than a keeper , it's a landmark
in audio DIY .

My redneck engineering of a V-fet case. The heatsink is going to be mounted on the outside. I placed it inside for picture purposes. That is a 300VA transformer. It looks small because the case is big and functional. I plan to make the amp mono inside one case at a later date. Also I am going to be installing 4 big motor run caps.
Thanks Walter for informing me. I honestly do not know which one to pick. Whatever Nelson decides to design is fine with me. Here is another picture of the heatsinks I am using. It is 8" high.
Hi WalterW
Fantastic 40th Anniversary Sony " One third " project.
Such build merits his own dedicated thread ?
Best regards
Many many thanks, Maestro! I will let you know as soon as I have received the kits; they are still on the way to Germany.
Cheers and best regards
