Anti-skating force adjustment
The anti-skating force must be adjusted corresponding to the downforce as
follows:
Downforce Groove in the stub (15)
10 - 14mN 1
st
from bearing rings
15 - 19mN 2
nd

20mN and bigger

Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub (15)
corresponding to the downforce applied to your cartridge and hang the thread in the groove of the
wire support (17).
Adjusting the azimuth
The cartridge needle must be vertical in the record groove in order to
trace the groove wall modulations correctly.
A small screw at the bearing end of the arm allows incorrect azimuth
to be corrected if your needle is not mounted exactly perpendicular to
the cartridge body (which is often the case).
Slacken off the screw just enough to be able to revolve the arm tube
without applying force. Note! Do not remove the screw completely!
With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e.
perpendicular to the record's surface). Ideally this should correspond to the top surface of the
cartridge body being parallel to the record surface, but in practice this is often not the case.
When you are satisfied that the needle is vertical, retighten the screw carefully.
Please note: Under no circumstances should the arm tube be adjusted with the needle still in the
record groove! Irreparable damage may be caused to the cantilever suspension! The arm must be
lifted to make each adjustment and lowered afterwards to check it.
Adjusting the vertical tracking angle (VTA)
Put a record and the record weight on the platter. When the needle is lowered into the record groove and
the tonearm is not resting on the lift arm, the tube of the tonearm should be parallel to the surface of the
record.
If it is not, loosen both allen screws in the tonearm base just enough to allow vertical movement of the
arm pillar without force and slide the arm up or down until it is parallel.
Carefully retighten the allen screws without applying excessive force (which would deform the arm
pillar) – finger tight is quite sufficient.
