For Sale Precision Preamplifier PCB

Things you have for sale.
Had some PCB's made for a preamplifier project. It is the "Precision Preamplifier" by Douglas Self, as described in his book "Small signal audio design". And after finishing this project, I have some boards left. The amp worked great btw, and I've only discovered minor error in the design (swapped "Hi Gain" and HI freq" text in slikscreen and too big lead spacing for two caps, but nothing that really mattered).

So if anyone is interested; I've got 4 pcs which I offer for €4 each + shipping (about €7 for Europe). There's schematic and BOM with Mouser part no's available too.

DM me if you're interesting.
