ABSTRACT:
An improved brush contact for a phonograph tone arm dynamic stabilizer. The contact includes bristles on a base, with free ends fanned in an arc. A portion of the bristles contact a record surface. Lateral movement of the tone arm across the record pivots the bristles and base, bringing new bristles into contact with the record surface.
