Don't see one easily available, but if the 3131 is similar, elektrotanya has that.

Welcome to the world of reverse engineering.

If it doesn't have double sided boards it can be done. I used to do it all the time, but that was a long time ago. I actually drew schematics of stuff I was working on. Not all the time.

First thing is to get up some pictures.

There is currently an original Optonica SA-4141 service manual for sale on eBay.
