Installing and Aligning the Cartridge
1. Remove the protective cover from the male pivot point on the arm base assembly.
To avoid injury, do not touch the male pivot point. It is
extremely sharp. In addition, skin oils can blemish and
cause corrosion to the assembly.
2. Place the JMW Signature Memorial Tonearm on its side on a foam pad.
3. For cartridges with threaded mounting holes, use the screws supplied by the cartridge
manufacturer. Other screws may not fit properly and may cause damage to the threads
and cartridge.
To avoid damage to the tonearm, use one of the washers supplied by VPI under the
screw heads.
4. For cartridges with pass-through mounting holes, use the hardware supplied with the
tonearm. Be sure to use washers under the screw heads.
5. The tonearm wires are color-coded as follows:
o Red right hot.
o Green right ground.
o White left hot.
o Blue left ground.
If your phono section inverts phase, the hot color becomes the ground color.
6. Using tweezers or fine-tipped pliers, grip the center of the red wire’s connector not
the wire itself and push it onto the cartridge’s right hot terminal pin. Connect the
remaining connectors in the same way.
To avoid damage to the cartridge, do not push the connectors all the way on.
7. Adjust the tonearm counterweight halfway back on its mounting to reduce the amount
of down force on the cartridge.
8. Place the JMW Memorial Tonearm Alignment Jig on the spindle with the narrow end next
to the pivot point. Tighten the screws of the jig so it fits snugly against the male bearing
shaft
9. Place the arm tube assembly on the lower pivot point, using caution with the 4-color
wire and Lemo connector. Set the arm in its rest.
10. If the cartridge has a guard, remove it.
11. Line up the red dot on the Lemo connector with the red dot on the receptacle on the
junction box. The Lemo connector can plug in only one way and should not be forced.
12. Swing the tonearm over the jig so the stylus is as close as possible to the dot in the
center of the grid. Set the counterweight for enough downward force to keep the stylus
from moving when resting on the jig.
