Might anyone have a Yamaha C-4 service manual or at least a circuit board diagram for the Function Board?
I already have the ones available from HiFi Engine etc and unfortunately they're close to illegible for reading some of the capacitor references. Very hard to confidently/easily recap without it.
Please feel free to dm me if you wish.

Of course free is nice but if you want the best quality, LEGIBLE schematics, and clear board layouts where all of the traces and components can be seen easily, sometimes you just have to pony up and pay for a proper manual. The benefits are that you will get color where color was used, schematics and layouts are on ONE sheet of paper and everything is clear and easy to read. I had to do this for a Yamaha T-7 tuner I just picked up. I couldn't find a clear schematic anywhere so bought an original paper manual. Nothing better. Just try not to fall into the trap of the scum vendors selling the same PDF's available for free all over the place.
 
I know it's been a while, but did you ever get your hands on a C-4 service manual? or a legible scan of one? There's one on eBay with a high price...
