Help with 1954 Seeburg HF 100R

The jukebox worked fine. I pressed selection A1. There was no record in there but now the mechanism is just stuck there. Whenever I turn the jukebox on, the mechanism just spins as if it is playing a record. When I press another selection, it will no move from A1. Any ideas of how to solve this problem?

Sure--simple--just press the reject button on the rear of the cabinet--or push the tone arm inward till it "rejects"--Do not force the tone arm--if it's stuck, write back, as it's another problem, requiring another "cure"-- Ron Rich
