Anti-Skate Tension Spring

The anti-skate mechanism relies on a precision-calibrated extension spring to apply a radial outward force on the tonearm. Failure occurs when the spring's mounting loops fatigue or the coil loses the specific tension required to counteract the inward pull of the record groove. Replacing this component restores the mechanical equilibrium required for the stylus to remain centered between the groove walls.

Tonearm Base Assembly

If the internal plastic cam or the anchor point on the adjustment dial has sheared, the individual spring cannot be re-anchored. In these instances, the entire tonearm pivot housing and anti-skate dial assembly must be replaced to restore the physical linkage between the user dial and the tonearm pivot. This is the standard resolution if the failure is structural rather than just a spring fatigue issue.

Anti-Skate Adjustment Dial

The plastic dial contains a molded-in eccentric cam that increases or decreases spring tension based on its rotational position. If the user forced the dial past its mechanical stop, the internal interface can crack, rendering the spring tension static regardless of the setting.
