YAMAHA XR658 Board Volume Potentiometer

Hello everyone,

could anyone know the type/value or mark, or better part number, of the potentiometer on the XR658 board for the YAMAHA PRS78/190 volume??

Any help will be appreciate a lot.


YAMAHA Part # is VQ320200. It’s designation is “A10K EWCEN0FH6 A14” which makes it a 10k log

Most probably a Panasonic model and either no longer manufactured or special design for YAMAHA

Looking at a current available Panasonic Part Number designation

A14 = Taper and Resistance
EWC = Product Code
other letters and numbers are other specs

We have the PSR-78 Volume pot available here:
