I will commission simple PCB with modification

[Bukowski26]

hi,

I looking for person who will draw simple PCB from schematic. This is Linkwitz preamp for WM61a with modification. I have to mean add GAIN potentiometr. That's all. I need the project to make PCBs in profesional made. Of course with description and files for drilling.

I need this PCB for measurement in live room in studio bulding.

Offer pleas send me for private message. I can pay to paypal. I have mainly schematic and ancillary schematics.

Regards!

This may be the one. System Test

I think we need the OP to specify a link to what he's copying, and we can ask Mr. Linkwitz

If you provide a circuit diagram I can quote you for it.
I already have a LR4 circuit in my system I designed a few years back.
Adding a pot would be easy enough.
Do you want me to get pcb's made too ?
China PCB Prototype & Fabrication Manufacturer - PCB Prototype the Easy Way do them dirt cheap if pcb is less than 10cm by 10cm.

So ... I need project witch not protected by author. Can someone draw simple preamp for WM61a with regulation GAIN? linkwitz preamp is really cool for measurement.

It should be made clear that circuits can only be protected by a Patent.

If there is no Patent then you can design your own PCB from the original schematic/circuit.

That's the point. I need PCB from the original schematic/circuit with add GAIN. If will be work fine I will be need clones guitar stompboxes PCB project.
