REPLACEMENT
STYLUS:
N75E
Model M75E-95G is a high qua!ity elliptical stylus Stereo phono
cartridge mounted in
a
retractile safety suspension system
to
provide
a
scratch-proof bounce-proof, teature to the operation
of
an automatic turntablk. The Model M75E-95G
is
designed speci-
fically for the Garrard SL95 Automatic Turntable.
The elliptical stylus cartridge is spring mounted in the pickup
head. A maximum needle force of
1%
grams
is
exerted on the
face
of
the record. Forces in excess of approximately 2 grams
will cause either the plastic safety bumper
at
the rear
of
the
cartridge
or
the plastic bumper in the stylus grip to come
in contact with the record surface and thereby protect the record
from needle scratches and protect the needle itself from damage.
Perhaps the most desirable advantage of all
is
that the M75E-
95G makes it possible to pperate the turntable
~p
situations
where
a
changer normally will not work well. These include such
adverse conditions as aboard a ship during
a
storm; in rooms
where modern dancing
is
done; and, in general, in any area in
which shaky
floors
or
unstable phonograph supports will normally
cause niistracking of the cartridge.
INSTALLATION
For
Automatic and Manual Play.
1.
Remove present pickup head and insert Shure Model into
phono arm. Care must be taken in removal and inserting of
the pickup heads not to cause damage to the stylus,
or
to
disturb the position of the leads.
2.
Set stylus force indicator to
"0."
3.
Balance arm as per Garrard instructions and set stylus force
indicator in the range of
1%
to
1%
grams.
In this case, the clearance from the record surface to the
plastic safety bumper at the rear of the cartridge will be
between
416''
to
$gn.
This range in recommended playing posi-
tion should be maintained even if it is necessary to adjust
the
1%
gram setting on the arm indicator: slightly. This may
be necessary due to the tolerance buildup in certain arm8 plus
slight inaccuracies in the arm-balancing process.
NOTE:
If
it is desired to play
a
stack of five records, the Clear-
ance
of
the safety bumper should be measured with
THREE
records on the turntable.
Sugges%Ecws
for
Cleaning
Your
SPylus
To
clean the stylus, use a camel's-hair brush (No.
2
size
or
smaller) dipped lightly in alcohol. The alcohol will remove any
sludge deposits which may have coated the stylus tip. The brush
bristles should be trimmed to
a
length no longer than
%
inch.
Always
brush the stylus with
a
forward movement from the
rear
(terminal end of the cartridge) to The front. Never brush
or
wipe
the stylus from front to back
or
side to side.
