THIS LISTING IS FOR 3 FREE PLAY/CREDIT ADAPTER PLUGS. FOR THE OLDER SEEBURG MODELS.. A B C G R M100A M100B. M100BL M100C HF100G 100W HF100R 100J 100JL................ PUT INLINE BETWEEN THE SOCKET ON TOP OF THE CREDIT UNIT AND THE CABLE COMING FROM THE SELECTOR..REMOVE THE COIN MECH PLUG FROM THE CREDIT UNIT AND MAKE SURE THERE ARE NO CREDITS REMAINING ON THE WHEEL...... HOW IT WORKS..KEYBOARD LATCH SOLENOID REMAINS DE-ENERGIZED UNTIL FIRST LETTER(OR NUMBER) IS PRESSED. THE SOLENOID REMAINS ENERGIZED UNTIL THE SECOND KEY IS PRESSED MAKING THE SELECTION COMPLETE....... THERE ARE VERSIONS OF THIS PLUG SELLING FOR $80-$100 THAT HAVE A TIMER RELAY BUILT IN SO IF A SECOND BUTTON IS NOT PRESSED WITHIN A CERTAIN TIME THE FIRST BUTTON WILL RELEASE..THIS COSTLY FEATURE IS NOT NEEDED..SEEBURG MADE THESE JUKEBOXES FOR COMERCIAL USE AND DID NOT BUILD THIS FEATURE INTO THERE JUKEBOXES,MY ADAPTER WORKS EXACTLY THE SAME AS HAVING THE JUKEBOX ORIGINAL(USING COIN MECH).
