ABSTRACT:
A stylus suspension for a phonograph pick-up cartridge. A first improvement includes an asymmetrically mounted ring and washer clamping the suspension block in a manner that dampens vertical compliance of the suspension. A further improvement includes a suspension block specifically adapted to accommodate the ring, thus more particularly defining the pivot point. In this instance the ring may be mounted symmetrically or as in the first improvement. A still further improvement includes an armature of reduced mass that, surprisingly, does not result in lessened performance.
