ABSTRACT:
The invention provides a method and apparatus for rapid and accurate stylus overhang positioning and tangential alignment with respect to a turntable. Accordingly a stylus locater plate having an aperture and a stylus positioning mark spaced therefrom is mounted on the spindle of a turntable. A pivot arm is connected to the locater plate on the other side of said spindle from the stylus positioning mark. The pivot arm and thus the locater plate, are then rotated around the spindle until such arm crosses over the pivot axis of the stylus arm of the turntable, to locate the mark in the turntable. The stylus arm is then pivoted toward the mark and the stylus cartridge is adjusted in the stylus arm to position the stylus in registration with such mark.
The locater plate is further provided with lines near such mark to guide the angular positioning of the stylus cartridge into a tangential alignment with the record grooves at such mark.
