Abstract
Large forces are developed at the stylus tip of a conventional phonograph reproducer arm because of excitation of the resonance of the arm mass with the suspension compliance. This paper presents an analysis of the problem and describes a reproducer-arm design in which mechanical resistance is introduced in the pivots. By this means, control of the arm resonance is obtained without increasing the stylus-tip impedance of the reproducer.
