Abstract: An improvement in a record player of the type having a base, turntable and a pivotally mounted, positionable tone arm comprising a device for selectively positioning the tone arm along the radius of a record to a repeatable position. The device comprises a first member extending from the tone arm and a pivotally mounted and selectively positionable and lockable stop member for preventing movement of the tone arm when the tone arm is lifted and moved toward the center of the record by having the first member contact the stop member. Placement of the tone arm down to the record plane permits the first member to pass over the stop member.
