Hey guys, I have an old keyboard from technics, called SX-K250 http://i18.ebayimg.com/06/i/08/a3/dc/69_1.JPG and along with time the sound started to deteriorate, it was as if overdriven, and less and less audible, trying to get through but being torn by some invisible grater. I need a service manual / schematics for this model, but where do I find one ? The Technics / Panasonic support is not quite good. cheers aero
