UNPACKING YOUR JMW MEMORIAL TONE ARM
This instruction manual was lying on a large foam pad. Remove the pad
and put it nearby on your work surface.
You will now see a number of things in plastic bags:
Allen wrenches for cartridge mounting and fine VTF adjustment
Hex nuts, and washers (for cartridge mounting)
Arm mounting and alignment tool
Damping fluid
Take all these items out and set them aside. Be careful with the damping
fluid. It should be kept sealed until it is used.
You can now see the arm tube and counterweight, with its delicate
Valhalla wire and Lemo connector, and the arm base assembly. If your
arm is pre-mounted on a tone arm board, remove the small foam piece
covering the "front" of the arm board. Set it aside with the other packing
material.
Now, here's the hard part. Leave the arm tube and arm base assembly
where they are -- safe in their packaging.
A. CARTRIDGE MOUNTING:
Remove the arm tube from the box (taking special care not to strain or
damage, the delicate 4-color wire and Lemo connector) and place it right
side up on the foam pad.
FOR CARTRIDGES WITH THREADED MOUNTING HOLES:
Use the screws supplied by the cartridge manufacturer to mount the
cartridge. Any other screws may not fit the thread properly and may
even damage the threads and cartridge. USE ONE OF THE SUPPLIED
WASHERS UNDER THE SCREW HEAD.
For all cartridges with pass through mounting holes use the hardware
supplied with the arm. Remember to use the washers under the screw
heads to prevent damage to the finish on the JMW arm. In this step, the
connectors will be attached to the cartridge's terminals. Disregard the
color of the insulators on the cartridge clips.
THE COLOR CODE OF THE WIRES IS AS FOLLOWS:
RED = right hot BLACK OR WHITE = left hot
GREEN = right ground BLUE = left ground
