CLEANING
THE
STYLUS
Dust
particles
often
build
up
around
the
stylus.
If
the
build-
up
becomes
excessive
it
will
result
in
noisy
sound
reproduc-
tion
and
will
eventually
shorten
the
lives
of
both
the
record
and
the
stylus.
Should
this
occur,
do
not
remove
the
dust
with
your
fingers
or
a
tool.
Lift
the
tonearm
by
its
handle
and
blow
the
dust
away
or
use
a
stylus
brush.
REPLACING THE STYLUS
For distortion-free sound reproduction, replace the stylus
after
1000
to
2000
LP
plays.
To
remove
the
old
stylus,
pull
the
stylus
down
and
then
forward,
away
from
the
tonearm
as
shown
in
Fig.1.
To
install
a
new
stylus,
insert
the
stylus
in
it’s proper place until a click is heard.
Tonearm
Stylus. Y
Fig.1
REPLACING THE CARTRIDGE
Insert a small screwdriver on the front retaining clip and
twist it a little until it releases the cartridge assembly as
shown in Fig.2. Unplug the four wires from cartridge. Plug
the four wires into the replacement cartridge. Be sure to
plug the wires (color coded) into the terminals as shown in
Fig.3. Place the lip of the cartridge (located at the rear of the
cartridge)
in
the
slot
in
the
tonearm
and
push
the
cartridge
up until it clicks into place.

Note: The FM IF circuit utilizes a non-turnable ceramic filter which establishes the IF bandpass. To insure symmetrical
turning and selectivity, the IF must be aligned precisely to the center of the filter bandpass, rather than to 10.7MHz
