Hi Sachin,

Please count me for 2 kits. I would like to add it before and after volume control.

BTW, how you search the part number on this site. I am pissed off with huge list as result of search.

Regards

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

PCB update

I have got price quote for Pass B1 pcb.Cost for 1 double sided PCB would be INR 330(including initial making charges).Please express your interest here,so I can order PCBs and JFETs.

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

 

[captrajesh]

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 -

Nelson Pass B-1 preamp kit

See the builds and tips on this page -

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 -

Class A matched SE J-FET stereo buffer kit ! | eBay

Hi Prasad,
I am following Audiocircle thread for BOM.As you know my technical knowledge is very limited,do we need two of this kind stepped attenuator for stereo?

Sachin

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.

This could be a better option IMO.
