13. Look down at the cartridge and align it between the lines of the grid. Be careful to align

the cartridge and not the tonearm headshell.

14. Adjust the cartridge mounting screws and the counterweight as needed until the

cartridge is centered between the grid lines and the stylus is resting on the dot of the

grid.

15. When the cartridge is properly positioned, tighten the cartridge mounting screws and

remove the alignment jig.

Setting the Anti-Skating – Two Solutions

Anti-skating 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 center of the record when the headshell of the tonearm has an offset angle.

Putting a stylus down on a flat, groove less record will cause the arm to move toward the

center 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 we 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. You now have the

option of installing a mechanical anti-skate for those that want it.

1. Adjust the counterweight so there is no down force on the cartridge.

2. 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.

3. If additional anti-skate is needed you can go to the mechanical anti-skate supplied but

not installed.

Setting the Tracking Force and Tonearm Height

Tracking force is adjusted by moving the tonearm counterweight forward and back on its

shaft. If your cartridge is heavy and the counterweight is all the way back, you can order a

heavier weight from your dealer.

The JMW Memorial Tonearm does not have a built-in tracking force gauge. We recommend

that you use the Shure Stylus Force Gauge or good digital gauge.

1. Place the Shure gauge on the platter with the notch against the spindle.

2. Follow the gauge instructions and set the tracking force according to the cartridge

manufacturer’s recommendation. We recommend always going to the high side of
