摘要

Arrangement for the adjustment of the vertical tracking force on a phonograph stylus. The arrangement has a rotatable adjusting element with a pinion meshing with a rack gear on the rear part of a flat tone arm, said adjusting element being connected with a counterweight disposed beneath the rear end portion of the tone arm. The rear portion of the tone arm is provided with a reinforcing member which also serves to prevent the counterweight from rotating with the adjusting element.
