multimoog missing osc b pcb

I've been bouncing around forums looking for advice. I'm the proud owner of a maimed multimoog -- it's missing the "tandem printed board" with oscillator B. It is essentially a micromoog with a bigger keyboard.

Any recommendations for getting a new PCB made? I've never had a pcb made. Not sure how to convert these schematics into something usable for a manufacturer like Olimex, http://www.4pcb.com/, https://oshpark.com/ ...

here are the schematics:

I'm wondering if anyone out there made project files usable for these manufacturers, like a CAD file or anything?
and, I'm feeling around in the dark, would you say this is this the best route to take to restore this multimoog?

I gotta admit, it sounds great as a micromoog, but I'm sad to see all these empty holes in the faceplate.

Hello,
You might be missing more than the tandem board if you have open holes in the top of the unit.
There are 2 small circuit boards in the Multimoog.
One is the tandem board and the other is the (pot/switch) top board.

You will need them both.

Good luck on your search/project.

Yes! I am missing the tandem and top board. I'm in the process of developing CAD files and parts lists.

Right now I'm wondering what the differences are between the Micro and Multi's main pcbs. I also have read that the filter on the micromoog was driven more than on the multimoog, and that the manufacturers changed it to accommodate for more power into the filter from a 2nd oscillator. I'm not sure how valid this is, or what is truth or internet truth.

Anyways -- if anyone knows the differences on the main pcbs between micro and multi, that will be helpful in my ill-advised detour in synthesizer rehabilitation.

I recommend Seeed Studio forPCB fabrication and assembly!
Their prices are the best and they offer online gerber viewer, and they will do assembly if you need it.

why not sell it and buy a complete one.
with the small price difference between micro and multi , you might be out cheaper and with much less hassle..
