A magnetic stereo phonograph pick-up cartridge is disclosed. An elongated stylus and an attached permanent magnet are resiliently supported by a molded rubber bearing block which surrounds the magnet and engages under compression with the inner side-walls of a stylus housing sleeve. The molded block is shaped to also serve as a cantilevered inertial damping member which is held in mechanical contact with the magnet.
