Seeburg M100C cancel button

Ron,
Does the M100C have an external button on the back panel (like the power or main volume control) for canceling a selection that is already playing? If it's not an external control is there one on the receiver or amp?
Thanks, Steve.

Steve,
Well, it did when it came out of the factory--but it's "hidden" --and also it can be un-plugged. Follow the wires from the WSR socket, if it has not been removed, you will find it about 3/4 of the way to the top of the cabinet, along the slide. Ron Rich
