Need Power/foot peddle Singer 690U?

I am in need of a the powercord/foot peddle for my Singer 690U - Magic bobbin Sewing machine. It was manufactured in Japan. I took my machine to a repair store to have it oiled and cleaned and tuned up and when I got my machine home the power cord was gone. The gentleman at the store cannot find it. He offered me $30 for replacement of the item. Can someone help me find one. I desperately need it so that I can continue sewing my bedspreads I am making. Thanks so much.
