Replacing the Cartridge
The life expectancy of the stylus tip is about 500 hours.
To maintain optimum sound quality and prevent
damage to your records, we recommend replacing the
cartridge before the end of this time duration.
Obtain a replacement cartridge from your Sony dealer.

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS AP-
PEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-
LISHED BY SONY.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety checks before releasing the set to the customer:
Check the antenna terminals, metal trim, "metallized" knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The "limit" indication is 0.75
V, so analog meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)

Make
sure
the
two
pins
on
the
bottom
of
the

are
properly
inserted
into
the
two
holes
in
the
motor,
as

and
turn
3
or
4
times
in
the
direction
of
the

Insert
the
headshell
into
the
end
of
the
tonearm.
Turn
the
locking
ring
in
the
direction
of
the

until
the

is
secure.

Getting
Started
Adjusting
the
Turntable
Before
attempting
to
play
any
records,
be
sure
to
complete
the
following
steps
to
properly
adjust
the
tonearm
balance,
tracking
force
and
anti-skating
dial.
Failure
to
complete
these
adjustments
will
result
in
inferior
sound
quality
and
may
cause
permanent
damage
to
the
stylus
and
record.

Turn
up
the
protective
cover
to
expose
the
stylus,
and
move
the
tonearm
to
the
space
between
the
arm
stand
and
the
platter.
Take
care
not
to
damage
the
stylus.
5
Balance
the
tonearm
by
turning
the
counterweight
either
clockwise
or
counterclockwise.
When
the
tonearm
is
properly
balanced
It
will
remain
level
with
the
platter
when
released.
It
should
not
tilt
in
the
direction
of
either
the
headshell
or
the
counterweight.

Return
the
tonearm
to
the
arm
stand.

A
properly
balanced
tonearm
has
a
tracking
force
of
zero.
Therefore,
rotate
the
tracking
force
scale
ring
until
"0
"is
aligned
to
the
index
line.
Restrain
the
counterweight
with
your
other
hand
so
that
it
does
not
rotate
along
with
the
scale
ring.

When
you
use
the
supplied
cartridge,
turn
the
counterweight
counterclockwise
one
full
rotation,
and
then
continue
turning
it
until
the
index
line
comes
to
1.
Since
one
full
rotation
of
the
counterweight
yields
a
tracking
force
of
3
grams,
this
adjustment
results
in
a
tracking
force
of
4
grams,
which
is
the
normal
requirement
for
the
supplied
cartridge.
You
can
set
a
tracking
force
of
3
to
7
grams.

When
optionally
available
cartridge
is
used
The
tracking
force
scale
ring
is
marked
in
0.1-gram
units.
One
full
rotation
yields
a
tracking
force
of
3
grams.

Set
ANTI-SKATING
to
the
same
value
as
the
tracking
force
scale
ring.
The
numbers
on
the
ANTI-SKATING
dial
indicate
the
number
of
grams
in
tracking
force.
Turn
this
ring
so
that
the
"0"

the
index

Turn
the
counterweight
counterclockwise
one
full
rotation,
and
then
