Abstract: In order to improve the performance of a stereo phonograph cartridge which includes a base, first and second piezoelectric transducers, first and second individual elastomeric blocks mounting the first and second transducers to the base depending downwardly in a cantilevered manner in horizontal spaced relationship, first and second separate elastomeric stabilizers mounted to the base in horizontal spaced relationship with each other and directly below the first and second transducers, a resolver having four connecting points contacting respectively to the first and second transducers and the first and second stabilizers, a pivot anchor coupling the resolver in a tensioned manner to the base, the pivot anchor being attached to the resolver at a point which is equidistant from each of the four connecting points, and a stylus bar extending from the resolver along the axis of the pivot anchor, the stylus diameter is reduced to thereby reduce stylus mass, the size of the resolver and stabilizers is reduced to per

Abstract: To provide for adjustment of stylus tracking force appropriate to a particular tone arm with which a phonograph cartridge may be used, the cartridge is provided with a compartment into which one or more weights may be placed. A damper is included for preventing vibration of the weights.

Abstract: An improved stereo phonograph cartridge which provides direct coupling between the stylus signal motion and right and left channel transducers with minimal distortion of the record groove modulation in which the transducers are held between elastomeric blocks with forces transmitted to the transducers by horizontally spaced contact points on a resolver on which the stylus bar is supported and which is anchored to the base with a flexible pivot anchor under tension with the resolver having a pair of stabilizers of an elastomeric material located in vertical alignment with the contact points on the resolver to form a second set of force transmission points with all points equidistant from the pivot point of the pivot anchor to result in a balanced arrangement such that right and left channel stylus bar motions will be faithfully transmitted to the transducers.
