I have ordered B1 BUFFER WITH KORG TRIODE PCB + FAIRCHILD JFETS from the DiyAudio Store. Is there a BOM as yet? Also I searched the thread but what are the power requirements? Looks like 24v but at what current?
There's a nice First Watt article with all you answers:

Hope it helps,

@yoshida,
i've got an answer, it hasn't turned out as i hoped. Thanks again!
Here ist the answer: "We regret to inform you but this product is not for international customers, available only for the domestic market."

Then why did they take my money? I am getting mine shipped to Norway, just like my nutube that I bought from the DIYaudio store as well.

Looks like the new board has twice as many JFETs over the Christmas board plus the R1 resistors ??. What do the R1 resistors do?

Does anyone have any recommendations for how best to jury-rig a simple socket for the Nutube that works well with the B1 PCB? There don't appear to be any commercial sockets for the Nutube.
(I know it has a phenomenally long life, but if one tube turns out to be excessively microphonic it would be nice to be able to easily swap it out.)

this thingie is already fragile enough and even thinking of pushing it in socket made me nervous
OK, I got it. Grand traditional Toshibas in the K slots and R1 is shorted with a wire if you can obtain the unobtanium in matched pairs.
The kit Fairchilds are specific, different Q1 and Q2 for the J slots and the included R1 resistors are necessary.
I have to make sure I plug those suckers into the right slots.
