8 ARM HEIGHT ADJUSTMENT
With the 1/16” ALLEN KEY slacken the set screw (29) in the ARM BASE FLANGE (22)
and raise or lower the PIVOT SUPPORT (21) so that the ARM TUBE is parallel with the
record on the turntable platter.
The Cartridge manufacturer’s recommended Vertical Tracking Angle (VTA) can then
be set by slackening the SET SCREW (29) and adjusting the height accordingly.
9 ADJUSTMENT OF THE UNI-LIFT
Adjust the ARM REST (9) with the 1/16” ALLEN KEY so there is clearance
when the stylus is resting on the record.
10 BIAS WEIGHT ADJUSTMENT
The BIAS THREAD LOOP should be attached to the BIAS ROD (19) between the plastic
spacers. The BIAS PULLEY WHEEL ARM (16) should be set so that the thread is parallel
with the ARM TUBE when the stylus is resting on the record. See Fig. 3.
It is recommended that the position of the BIAS THREAD LOOP between the spacers
on the BIAS ROD (19) should initially be halfway along the rod. The final position of
the BIAS THREAD LOOP should be determined by using the Hi-Fi News Test Record.
Set the MAIN WEIGHT (11) and the RIDER WEIGHT (7) to the cartridge manufacturer’s
recommended tracking force. It is essential to use a Stylus Balance Gauge to achieve
accurate pressure. Azimuth (i.e. the angle of the HEADSHELL) is adjusted and can be
set by rotating the MAIN WEIGHT (11).
