Hi Om,
I am following this thread for Pass BOM Nelson Pass B-1 preamp kit
the above link has give Pass B1 BOM with suppliers link like Digikey, part connection etc.I search manufacturer's part no on element 14,if particular part is not available than search with part description.There are very few parts like cross over caps not available with Element14.I have already found a source for matched JFETs for B1.There are very few components which needs to be imported.
BTW has anyone decided on enclosure for B1,it would be great if someone can make them locally.
Regards,
Sachin

I'm in Sachin. BTW, ensure right thickness of the tracks which would make quite a difference in SQ.
Thickness of the soundtracks?
--G0bble
Not sound tracks Gobble I'm referring to the metal tracks no the PCB; They are measured in microns and their thickness would have a bearing on the SQ.
There's an excellent B1 build thread over on audiocircle -

Sachin, there are a couple of ebay items, the stepped attenuator,
and the B1 kit from Jim's Audio. If you can get a group discount on
those, that might be worth considering too -

Sachin,
Yes, you would need two of them. From the picture they are not ganged stereo pots.
Check, you may find ganged dual pots for stereo use.
Cheers.
