1/4-inch phone jack, 4-pin PCB mount

Hi…i’m from Indonesia looking for a 1/4 inch phone jack, 4-pin PCB mount, for my Yamaha P140. Is it possible that the parts are available now and can order online to Indonesia?

My problem is sustain remains active even though I don’t step on the pedal. so I suspect the problem is with the pedal jack port. I have changed sustain pedal 3 times, the problem remains the same. Thanks…

Does the sustain stop when you step on the pedal? Could be you are using the wrong polarity of pedal.
