VPI JMW 12.7 Tonearm Anti-Skate Upgrade
Anti-Skate is one of the least understood forces acting on a tonearm. Skating force is created by friction between the stylus and the record, causing a force vector in a direction towards the centre of the record when the headshell of the tonearm has an offset angle. Putting the stylus down on a flat, groove less record will cause the arm to move toward the centre of the record.
Arm manufacturers have tried to compensate for this force, but that is impossible because the force is constantly changing as the music and velocity change.
VPI has conducted careful listening tests and determined that every tonearm they tried sounded better with its mechanical anti-skating disabled and the tracking force very slightly increased... VPI has a unique solution to anti-skating: the coiled wire of the JMW Memorial Tonearm acts as a spring and pushes the arm back without affecting the sound quality. The new VPI JMW-12.7 Tonearm Anti-Skate Upgrade now gives you the option of a mechanical anti-skate device!
If you have older scout/tonearm combo that has "silver" junction box, new mounting will be needed.
