surrounding the bearing shaft till the fluid level reaches the groove line inside the reservoir.
In addition put 1-2 drops of fluid into the cup on top of the bearing shaft. The level of
damping is chosen to suit the best cartridges available but you should experiment, especially
with cheaper MM cartridges.
Bias adjustment:
Catch the string loop onto the hook which is at the back of the tube base. Be sure that the
string runs in the groove. Adjustments are made by moving the small counterweight after
releasing it with the Allen key (1.5mm). The maximum position is for 2.5 g tracking force
and the minimum is for 1 g. Finer adjustment should be done using a test record. Consult
your dealer.
Fine adjustments:
Re-check and readjust the tracking force, VTA and azimuth if necessary. For more precise
adjustments, play the cartridge for 5- 10 hours and then readjust. The cartridge will need
about 50 hours playing to settle down for the best sound.
3. Adjustment of VTA:
It is extremely easy to set up VTA on this tonearm. Just unlock the lever at the back and
rotate the VTA knob. VTA knob rotation CW- VTA down (Fig.1)
VTA adjustment between any two lines is 0.1 mm (the whole rotation is then 0.8 mm) which
allows for very fine repeatable adjustment. The rigidity of the assembly is such that even in
the unlocked position you will not feel slack. Move the tonearm VTA to the desired height.
Simply lock the lever back with gentle force. Observe the 1 mm scale at the left hand side of
tonearm tower (Fig.5). If you run out of range (10 mm), then you must reposition the tonearm
height in the armbase. However take into account what is the optimal VTA by listening.
Once you find out the correct VTA, rotate the outer ring of the VTA main knob and position it
into null position. This is now your starting point for very fine tuning.
