Let's see if he comes back asking for help if he has problems with his board! It's happened before. 😀
And if he has issues I would like to believe folks would help him.
Just my opinion but when someone asks if the files are available I am pretty sure they know it is for personal use.
When I received the files for the Pearl 2 from the gentleman from Pass who created them he never stated to me that they were for my own use because I believe most folks here are honest and know that.
Just my opinion, but you know what they say about those.

Hard to see why one would pass up the bargain (no pun intended) from the Pass Store. Your get an authorized board plus JFETs tested by the master himself. Priceless!
That is were I got mine but some folks probably do not mind doing the testing of the JFET’s and could be looking at beefing up the boards etc etc.
Hello all, it is 55 usd shipping , so it’s difficult for a 40 usd item ....
No problem, I understand you all.
Best regards, Gilles.

Point taken.
When you do get it up and running, it'll blow you away. It's that transparent!
My B1 puts my old Parasound pre to shame.

If I may ask were you saying Mixi’s price of 40 dollars was o much?
Non sorry, I spoke of the official shop.
Board + shipping = near 100 $
I didn’t know Mixi price.

It's not a "real big" issue other then some guy making money with a design that is not his IP - I think NP has other things to take care of!
Looking at the actuel JFet prices for 2 matched pairs (or maybe this is the "same-sex" version?) I would say I'd jump on the offer from the Pass-Diy site anytime and would proudly show it off - I would send an email to ask if a more adequate shipping fee might be applied though!
I might even order one although a 2 channel attenuator is of no need to me now that you point me to it!

Damn, that shipping is a killer. Thank you for the reply.
I think we all know who’s IP it is, but as getting at; many people have asked about the files and were given what I consider a normal reply.
How many people have you seen here stealing his IP for profit?

@gillougillou: shipping from PassDIY store to my U.S. address is $7.40. I can forward it to you for an additional $15 - that's USPS cost + packaging, I am not making money on it. The total affair would be $65 to you. PM me if interested.
You can also use the official gerbers and order one PCB from e.g. EuroCircuits.be for about the same money. No JFETs would be included, though. Yon can also shop Chinese PCB vendors and get lower prices for a minimum order of five PCBs than EuroCircuits charges for one, even including DHL worldwide shipping. Or, as Stanislav pointed out, you can build it on a perfboard - maybe less elegant, but once inside an enclosure, there will be no difference.
Re eBay $9 boards - what I see offered for sale is not using the original gerbers.

Is there a way to increase the gain by changing resistor values?
Plain B1 is a source follower with the maximum gain of ~1. To have more gain, consider, for example, the version with Korg triode.
B1 R2
Hi, I would like to build the B1 R2 buffer, schematc added, but I have some doubt, first the voltage of the power supply, I’ve seen from 10v to 30v.
The other questions I have 2 very matched pair of 2sk170/ 2sj74 with idss 4,12, should be enough?
Many thanks

If I'm not mistaken, the B1 runs on 18V.

Thank you so much but the R2 use 2sk170/2sj74, please look the schematic I added
Where did you find the B1 R2 schematic? Maybe there is more documentation available in the same location. 😉
I've built the B1, but am not aware that is a R2. It looks like a typical Pass schematic, though, so maybe I missed the announcement. Do you have PCB's?

Maybe you should be asking questions in the thread dedicated to the B1 Rev.2 buffer: Here
