Convention Paper

Overcoming Record Warps, Low-Frequency Turntable Rumble, and Acoustic Vibration Feedback in Phonographs

Authors: Clunis, Kenneth; Kelly, Michael J.

AES Convention 51 · Paper 1046 · May 1975

Abstract

Certain classes of warped records cannot be tracked by ordinary tone arms, and even those with elaborate vibration dampeners or viscous damping often result in stylus displacements which seriously affect the sound quality. By detecting and controlling the absolute stylus force, many of the bothersome low frequency turntable problems can be solved. A stylus force regulator system employing feedback control is described.
