REPLACEMENT OF STYLUS
A modern lightweight pick-up is a sensitive instrument and must
be handled very carefully to avoid damage.
A sapphire stylus has a long life if used carefully. Only records
in good condition with clean, dust-free surfaces should be used
since worn surfaces may damage the stylus. A worn or damaged
stylus causes harsh reproduction and increased surface noise and
should be replaced immediately.

CARTRIDGE MOULDING
The record player uses a type GC8 pick-up, with two sapphire
styluses.
To replace a stylus first remove the pick-up head*. Then
insert the blade of a penknife under the middle of the stylus shank
(see Fig. 4) and gently ease this away from the cartridge moulding.
Carefully press the new stylus into position so that the back of
the stylus shank is firm in its socket and the front clasps the
actuator. Replacement styluses for the GC8 pick-up are as follows :-
Standard (78 r.p.m.)—stylus GC8-3 (colour code green).
Long playing (16, 33, 45 r.p.m.)—stylus GC8-1 (colour code
red).
