Would any one know how to get a stereo jack for my PSR-740? It has the name JALCO with no visible part no. It has failed to make good contact inside. Then I opened it without unsoldering it and CAN NOT get the plastic cover back in. It is too precise to fit it back. If I have the part, I can unsolder the old one and put a new one in. JALCO is a Japanese manufacturer in the web but does Yamaha sell such parts? From where? A service center?
