ADC Accutrac 4000 Turntable

item condition THE ITEM IS IN GOOD USED CONDITION . THE DUST COVER AND THE FRONT AREA WITH THE CONTROL KNOBS HAS SMALL SPECS OF WHAT I THINK IS WHITE PAINT OTHER THEN THAT THE TURNTABLE SHOWS MINOR WEAR . I THINK THE LOCK FOR THE ARM IS BROKEN . ITEM POWERS ON TABLE DOES MOVE , THE SPEEDS SEEM TO WORK BUT THE ARM DOES NOT COME UP OR MOVE I THINK IT WILL NEED REPAIRED  . I DID NOT CHECK ANY OTHER CONTROLS ..
