Spr Ford 510

many thanks for the suggestions. I will try everything that you have noted and keep my fingers crossed. I do realise that a technical repair to the circuitry could cost more than the unit is worth, but heres hoping.

My Casio CTK5000 keyboard will no longer sustain notes when using the sustain pedal. This is a sudden occupancy. I have checked the pedal with a meter and it is ok. Does anybody have any input?
