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.
Fine VTA:
The correct height of the tonearm is different for different cartridges and tracking forces. It
could be above or below the theoretical 'parallel tube' position for up to 4-5 mm. If you are
above the optimum height the sound becomes bright and thin and if below, the sound could
be bass heavy and not open. Feel free to experiment or consult your dealer.
Fine Azimuth:
The starting position is in a line with its mirror image. For fine adjustment a test record and
oscilloscope are needed. In the thicker counterweight, however, there is a small screw on the
right, which can be rotated using Allen key (3 mm). Rotation of the screw will slightly
change the azimuth. Counterclockwise rotation tilts the cartridge to the left and vice versa.
Counting rotations enables you to listen to improvements in focus and to return to the original
position. If necessary consult your dealer.
Cueing device:
The height of the cueing device can be adjusted with Allen key (1.5 mm).
Tube rest:
The height of the tube rest can be adjusted with Allen key (1.5 mm).
