A friend of mine has a piano shaped Grafonola with an electric motor. The speed control does not work correctly. It uses a cable not unlike a bike brake cable, i.e., a solid wire inside a springy wire outer core. It looks like moving the speed control knob should move the inner wire of the cable which would then move the yoke with the friction pads that hit the governor disk. The problem is that the whole cable will move. The ends of the cable assembly unscrew from the assembly. I'm wondering if a DPO lost some internal parts. Does anyone have a working version of this set up? Are you willing/able to take it apart to photograph its components? The innermost parts of the ends come apart if you push out the little pin but it is probably a bit difficult to reassemble. I have not gotten that far yet.
