The VPI Prime Feet improve the vibration control of your turntable and equipment. The Prime's cone foot and isolation platform system greatly reduces performance-hindering vibrations and allows for the optimal operation of your audio equipment. They can be installed on nearly any VPI turntable as an easy foot-upgrade, or be placed under virtually any piece of gear for improved performance.
The VPI Headshell Weight, designed for use with VPI JMW tonearms, allows lighter cartridges to be used on heavy tonearms, such as the 10" and longer JMW tonearms. the Headshell Weight may also be spec'd for use on very light cartridges with an assortment of tonearms.
This upgraded motor rotates at a slower speed than the stock motor, offering less vibration, lower distortion and greater accuracy. VPI labels this a 300RPM motor to eliminate confusion, since it serves the same function as the 300 RPM 120V/60Hz motor.
You will see three rubber rings on the straight shaft; these are used to set the anti-skating force.
The two rubber rings on the shaft with the grooves are used to set the height of the monofilament. Set the rubber ring on the lowest groove if it is not there already and slip the loop of monofilament over the grooved shaft. Push the second ring down to lock the loop in place on between the first and second groove. Try to keep the monofilament as level as possible but don't go crazy, it is not audible and causes no problem if it is slightly off level.
You can adjust the settings of the mechanism using the 1/16" Allen wrench provided. Adjust it so the arm can travel to the inner grooves of the record without the mechanism pulling it or causing it to skip grooves.
Minimal anti-skate force is needed do just enough to keep the image stabilized and the cantilever centered in the groove.
