Mounting or exchanging a pick-up cartridge
Instead of the factory-supplied pick-up cartridge any
other cartridge with standard half-inch mounting
holes and a weight between 3 and 10 grams can be
installed. To do this loosen the collar-lock (9) and
pull off the head shell (Fig. 7). Unscrew the cartridge
and carefully remove the coloured signal leads from
the cartridge pins with a pair of tweezers. Screw the
new cartridge onto the head shell but do not tighten.
Attach the leads to the pins while observing the
correct coding.

Please note: The example shown in Fig. 8 is appli-
cable only for the pick-up cartridge OMB 10!
For the precise adjustment of the so-called stylus
overhang push the head shell with cartridge into the
supplied mounting gauge. The adjustment is correct
if the stylus is flush with the V-shaped recess in the
gauge as viewed from above. When viewed from the
side the stylus should be seen within the rectangular
recess of the gauge (Fig. 9). Adjust the cartridge in
the head shell until the correct positions are
achieved. Lastly, tighten the mounting screws, put
the head shell with cartridge back on the tone arm
and tighten the collar-lock (9).
ATTENTION!
During these mounting and adjustment procedures Fig. 8
you must be very careful not to damage the delicate
stylus and cantilever by uncontrolled and brisk
movements.
Replacing the stylus
Any stylus is subject to wear even under normal
playing conditions. Therefore, it is highly
recommended to have the cartridge, respectively its
stylus, inspected after about 500 hours of playing.
This is because a worn or damaged stylus will
eventually damage your precious vinyl records!
In order to playback vintage shellac records (78's)
with optimal results the original stylus should be
exchanged with a suitable special stylus for shellacs.
Please consult your THORENS dealer for further
information and details.
