I have 8 sets of PCB's made by PCBway using files from Nelson Pass.

$10 each or $15 for a pair.
Shipping in USA is only $7.20 via USPS Priority mail
Shipping overseas isn't worth it considering shipping could be 2 - 4 times PCB's price.

Using Nelson's BOM from the article, the part numbers have changed due to RHOS, yet they were easy to find using DigiKey online catalog. My power supply is finished and the Line Stage board is complete. I'm now working on the enclosure for the line stage.

@rajesh - the pdf is on the PassDIY website and the components are nothing uncommon. Capacitors, resistors, a few zener diodes and IRF610 and 9610 mosfets.

It's an unfortunate trend in DIY that people forget the circuits of the past and only build the most recent designs while the commercial preamps from 20 years ago still regularly sell for hundreds or thousands of dollars on the used market.

If you get the chance to build this one you will not think it sounds bad. It is class A and designed by Nelson Pass after all. The best part is there are no expensive or difficult to source parts in this one.

Thanks for the heads up.

I heard lot of good words about it. My curiosity made me ask the noob question. Too bad, looks like they're all gone.

I still have two Line Stage boards available. I was going to keep one for a spare, the preamp works so well I've decided not to keep it. Price is $10 for each board and $7.95 for shipping via USPS Priority mail.
PM me for PayPal payment info.

I'm using a linear 10K four ganged 24 step pot using Vishay Dale resistors and a Log 5K four ganged pot using Vishay Dale resistors.
I bought a blank 4 ganged pot which I plan on making a linear 5K pot, once again using Vishay Dale resistors. Not looking forward to that project, 96 resistors to solder to a plastic ganged stepped pot. This is why engineers create machines, so that people don't have to do work like this.
