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.
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
headshell 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 Ortofon OMB 10!

Put the supplied mounting gauge onto the platter
and align the cartridge in a way that the stylus tip
is exactly above the crossover point of the auxiliary
lines and the cartridge body parallel to the auxiliary
lines. After the cartridge has been properly adjusted
tighten the screws carefully.
Adjusting the start position of the tone arm
The start position of the tone arm has been adjusted in the factory. However if there is a
deviation it may be readjusted by turning screw (9, Fig 11) to either left or right until the stylus
can be lowered exactly at the lead-in groove of the record.
Electrical Safety
This device is in conformity with international safety regulations (IEC 65) and
EC regulations 76/499/EWG.
ATTENTION!
During these mounting and adjustment procedures 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.
