S80 JK Board Broken L/Mono R output


I just bought a few jack parts from Syntaur - and I am eager to start soldering them on and replacing the old one. Prior to any work - does anyone have a schematic for the xv914 board? It is not in the online manual sadly. :confused: I just want to make sure it is supposed to go where how I understand it without the schematic. Difficult to find parts for this - don’t want to ruin it!

Thank you in advance!

If you are just replacing phone jacks, just make sure the solder pin configuration is the same from the old one to the new one. Or do you have other questions about the jack board? The schematic for that should be in the Service Manual, but you probably have to be an authorized Yamaha service center to have access to that.
