ABSTRACT:
A phonograph record player or changer having a turntable spindle whose lower end is journalled in a combined thrust and radial bearing, while the upper end of the spindle is located by two contact regions on a sleeve bearing. The upper sleeve bearing is formed with two portions extending toward the center of the bearing bore arranged so that a resultant of all of the transverse forces on the spindle passes between the two contact regions, thereby producing a phonograph with reduced wow and flutter.
