4. Assembling
the counterweight
As a precaution against damage in transit, the counter-
weight
is
packed
separately,
already
threaded
on
the
removable
back
tubular
part
of
the
arm
with
the
set
screw.
Slide the back tubular part with the counterweight
‘onto the pick-up arm extension and lock it in position
with set screw.
For balancing the arm move the stylus force adjustment
lever back as far as possible to the abutment of the
lower end of the scale. Move the lowering device
slide bar to the “play” position. Position the arm
80 that the stylus tip is between the arm rest and the
turntable platter.
Turn the counterweight with the right hand, while main-
taining the lateral position of the arm with the left hand
to avoid damaging the stylus, until the arm assumes a
horizontal position, i.e. the stylus is at record surface
level.
5.5. Stylus force adjustment
After balance of the tone arm has been achieved, slide
the stylus force lever to the prescribed weight on the
stylus force scale as recommended by the cartridge
manufacturer. Fig. 4.

5.6. Anti-skating adjustment
The setting of the anti-skating force depends mainly on
the applied stylus pressure. At the TP 25 tone arm it
can be adjusted by fixing the nylon thread which is led
through a hole in the tone arm mounting board in one
of the three different notches. The highest anti-skating
force is applied when the nylon thread hangs in the
outer notch.
Furthermore, the force can be decreased by un-
screwing the lower part of the antiskating weight.
