Abstract
A cueing control is provided for a phonograph turntable of the type including a frame, a record supporting disc affixed to the frame and mounted for rotation about a central axis, and a tone arm having a cartridge assembly affixed to one end thereof. The cueing control comprises a post mounted to the frame for vertical movement and having a cradle affixed to its top end designed to underlie portions of the tone arm. The bottom end of the post is engaged by one end of a bimetallic element which, in turn, is cantilevered to the frame. A heater is positioned adjacent to the bimetallic element so that the element can be heated and caused to deflect to thereby shift the post vertically.
