Default DIY D1 I/V Stage from Pass Dac PCBs for sale

I have a few pcbs to sell.
Its the D1 I/V stage on a pcb I made for me. I made a few extra pcbs to get the cost down so if anyone is interested please post for how many you are interested in.
I have a layout, parts list and description on pdf for those who want to build these pcbs.

The mains PCBs cost 12,50 Euro a piece and the Power Supply boards 5,50 Euro.

You can see the schematic below.

This is what the prototype boards look like.
I have been using them for almost a year now and they work superb.
The sound is fantastic.
The difference with the new ones will be a few small corrections in the positioning but they are the same.
There will be a top print for the placement of the parts which was not the case in the first ones.

Each board has to circuits on it.
In the schematic the identical parts are marked with A and B.
Only 2 resistors and 2 capacitors are common for the 2.
That means that if you want stereo singel ended output you need one board from each. 1 Main board and one power supply.

If you want a stereo balanced output you need 2 boards from each.
2 main boards and 2 power supplies.
