We could go on discussing the pros and a con of how much anti-skate is correct,
but the sonic answer is very simple. Adjust the wire as mentioned above until the
tonearm drifts outward when set to neutral balance.
balance floating tonearm towards the center of the record, it should push back out
towards the rim of the record. Very little force is needed to do this, and the wire
acts like a spring to supply this force.
If you try adjusting the anti-skate with a groove-less record or a test
record you will ruin the twist in the wire and void your warrantee
Double check the horizontal balance, lateral balance, and tracking force and adjust
as needed.
Increase the tracking force by 1/10 of a gram above the cartridge
manufacturer's highest recommended force.
G. ARM HEIGHT:

THE
LISTENING.
Unlike many tone arms, the JMW's height is both easy and repeatable to vary. The
knob next to the bearing housing bears a scale numbered from zero to ninety-nine.
Below the knob there is an index mark engraved on the front of the support pillar.
Rotating the knob clockwise lowers the arm and rotating it counterclockwise raises it.
Set the arm height as follows:
Place a record on the platter surface. Lower the arm onto the record and make the
arm tube parallel to the record surface by rotating the arm-height knob as needed.
This is a good initial setting. You may wish to vary it depending on the cartridge
you are using and or the particular record being played. The knob's scale makes it
easy to return to a previous setting by making a note of the number above the
index mark and the number of complete turns taken.
The old wisdom, which had the arm tube parallel to the record surface, assumed
not only that all cartridges had the same internal geometry and stylus rake angle
but also that all records were cut with the same equipment set the same way. The
idea was that everything would line up properly with the arm parallel to the record.
This is not true and the VTA should be adjusted for best sound in your system.
Rule of thumb: Raising VTA lowers bass and increases treble.
VTA increases bass and decreases treble.
H. CONNECTING TO THE PREAMPLIFIER/AMP
ONLY USE INTERCONNECTS THAT ARE SHIELDED AND PROPERLY GROUNDED. NON-SHIELDED
INTERCONNECTS CAN HUM AND PICK UP RF.
The connector block at the rear of the arm base has, in addition to the Lemo
receptacles two phono receptacles and a ground connector.
