On Stabi S 12 turntable:
Release the VTA screw which holds the brass pillar, while holding the bearing base. Then
reposition it and lock it back.
Armbase:
Release the VTA screw in the armbase while holding the bearing base and reposition it and
lock it back.
Azimuth:
Level the turntable horizontally. Any change will affect the azimuth. Observe the mirror
image of the cartridge on the record and adjust the tilt of the cartridge so that the mirror
image and the cartridge will be vertical and straight. For this adjustment, rotate the thinner
counterweight. If you find that the tilt is excessive, then first rotate the thicker
counterweight and then make fine adjustments with the thinner counterweight. See Page 3.
Tangential geometry:
Adjust the geometry of the cartridge in the headshell so that zero point will be on the
protractor in both null points (66, 120.9 mm). Consult your dealer .
Oil for damping:
Carefully lift the tube base, bearing in mind the length of the wires and put it on top of the
platter. Cut the tip off the nozzle of the PVC bottle and squeeze to fill the reservoir
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 made 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. Counter clockwise rotation tilts the cartridge to the left and vice versa.
