The manual for the 9" VPI tonearm states:
"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. You now have the option of installing a mechanical anti-skate for those that want it.
-Adjust the counterweight so there is no down force on the cartridge.
-Swing the tonearm toward the spindle and release it. The arm should swing out toward the outer edge of the turntable.
If you try adjusting the anti-skate with a groove less record, you will ruin the twist in the tonearm wire and void your warranty. Do this with the mechanical anti-skate if you want that much anti-skate.
If additional anti-skate is needed you can go to the mechanical anti-skate available from your dealer."
The new manual for the 10" and 12" adds this:
"As mentioned earlier, the arm wire applies the anti-skating force. The degree of force applied can be adjusted, to increase anti-skating force give the connector a counterclockwise twist, unwinding the wires natural twist. Likewise, to decrease the force, give the connector a clockwise twist, winding the wires natural twist. Remember, the Lemo connector can only be 'adjusted' in increments of whole turns. If it is not, its key will not line up with the groove in the receptacle.
If you try adjusting the anti-skate with a grooveless record you will ruin the twist in the wire and void your warrantee.
This is all you need for anti-skating."
So, the wire definitely will affect tracking. It is interesting that the manual for the 9" warns against using a grooveless record to adjust anti-skating, but never says anything about about twisting the wire to adjust anti-skating.
Furthermore, though the manuals basically say to do nothing, it says to twist the wire to adjust anti-skating and that's all you need, but VPI makes and sells a mechanical anti-skate device ($100). I have the mechanical device. It is a kludge, but it works for me better than adjusting the wire.
