End Editor's note.

Hi to all,

for those who want to have a optical and technical perfect solution for the Lightspeed Attenuator, i have made a real nice PCB.
It is a 2-Layer Design to seaprate the Audio-Lines (Bottom Layer) from the Electrical-Lines (Top-Layer).
The regulated 5V PSU is included. Furthermore i made the Audio-Lines extra wide (1mm) and choose 70µm copper to get minimal loss.

At the moment the first units are in production and the Pre-Order can start.

The PCB has the following data:

Material: FR4 - 2mm
Layers: 2
Board size: 87x54 mm
Surface finish: Immersion Gold
Copper weight: 70µm
Soldermask: Both sides - blue
Silkscreen: Legend on top

The price will be as followed:

Professional 2-Layer PCB: $15
Worldwide shipping: $ 4
paypal fee: 3,9%

I have add the BOM-List for the PCB-Parts. There you can see, where to order the necessary parts and the PCB as a line-drawing.
I will add some picture, after the first PCB´s arrived!

Pre-Orders only at: diyaudiopcb (at) gmx.com

Best regards to the community,

The Pre-order is pending till i have an official statement that the developer of the circuit, George Stantscheff, had no problems with it.

My apologies to that.

I made a arrangement with George Stantscheff and so the Pre-Order can start again!

My thanks to George!

$19.74, yes? (say $20)?

Is the board 100% now, pot correctly orientated?
