Abstract
A phonographic pick-up cartridge comprises a wire 15 mounted in an elongated, shouldered cylindrical sleeve 8 disposed in a mating cylindrical cavity in a stylus support 7, the forward end of the wire extending through a resilient, compressively stressed damper ring 6 and being secured to the rear end of a cantilevered stylus arm 18. The support 7 may be diagonally split and hinged along one edge, or formed with a recess 24 and mating insert piece 25, and is closed over the sleeve 8 during assembly. By properly dimensioning the components the damper ring is appropriately stressed during assembly, and no initial wire tensioning adjustment is necessary.
