Abstract
A phonograph cartridge replaceable stylus assembly is provided. The assembly comprises a housing having a nonmagnetic tube affixed thereto. The tube has a forward end and a rear end extending outwardly away from the housing. A nonmagnetic stylus arm extends through the tube forward end. A jeweled stylus is mounted to the front of the arm. The rear end of the arm passes through an elastomeric damper positioned within the tube. The damper serves as a universal pivot joint for the arm. The damper comprises a cylindrical member having a forward edge and a rear edge with one of the edges engaging the tube and the other edge being free of the tube. A magnetic member is positioned within the tube secured to the arm and adapted to move therewith in response to motion of the jeweled stylus and following the grooves of a record.
