Abstract
An improved tone arm mounting system, for improved damping of tone arm system () vibrations. Tone arm system () is supported by tone arm pedestal (). Adjuster screw () is affixed to the bottom of tone arm pedestal () so that adjuster screw axis of revolution () passes through or near tone arm system weight center of gravity (). Adjuster screw (), by threaded means, rotatably receives adjuster wheel (), which is thin and is large in diameter, for easy access to its outer edge for manual or mechanical operation. Rotation of adjuster wheel () on adjuster screw () changes the height of tone arm pedestal () and thereby changes VTA (). The tone arm system () is supported by arm board () without vertical connection to arm board () thereby damping mechanical vibrations and improving signal quality. A lightly loaded vibration damping washer () can be used between thrust bushing () and adjuster wheel () to damp or filter transfer of mechanical vibrations from tone arm system () to arm board () and back into tone arm system ().
