The turntable platter of this set also works as part of the rotor
of the motor. Never remove the turntable platter unnecessarily.
Never stick dust or iron filings to adhere to the magnet rotor.

33-1/3 r.p.m. at 60 Hz
@ TONEARM RETURN ADJUSTMENT
SCREW
In some cases, the tonearm will tend to return to its rest position
before the record has finished playing. In other cases, it will to
return to the rest position even after the record has finished
Rotation of this screw in the proper direction will correct either
condition.

STYLUS
SET-DOWN
ADJUSTMENT
SCREW
To be adjusted if the tonearm fails to set down at the right start-
ing point at the beginning of the record. For access to the
screw, a rubber cap above it must be removed.
Clockwise rotation ...This will move the set-down point out-
ward, away from the record center.
Counterclockwise rotation...This will move the set-down point
inward toward the record center.
® ARM LIFT ADJUSTMENT SCREW
When the tonearm is removed from the record surface via the
tonearm lift, the space between the stylus tip and the record
surface should be between 5 and 10 mm (between 3/16” and
25/64"), If this height needs adjustment, turn the screw along the
KNOB
Turn this knob to the same number as the stylus pressure ring
indicates.
Skating force is the frictional force caused by contact between
the tip of the stylus and the record groove, and is applied to the
stylus as a side pressure depending upon the relationship of the
geometrical position of the tonearm.
This force results in an unbalance of the contact pressure be-
tween the stylus tip and each groove wall of the record, an
increase of distortion, a decrease of separation characteristics
and abnormal wear of the stylus tip and the record grooves.
For this reason, it is necessary to compensate this skating force.
This anti-skating force mechanism performs this compensation
function.
The quantity of anti-skating force is in proportion to the stylus
pressure and, therefore, it should be adjusted according to the
stylus pressure.

3 HOW TO ASSEMBLE
INSTALLATION OF THE
TURNTABLE PLATTER
Install the turntable platter to the motor shaft.
Place the turntable sheet on the turntable platter.
NOTE
This set is especially designed for a direct drive player system.
Therefore, the rotor, which is rotating part of the motor, is con-
nected
directly
to
the
turntable
platter.
(The
magnet
of
the
motor
is
attached
to
the
turntable
platter),
For
this
reason,
to
maintain
the
high
performance
described
in
the specifications,
care should
be taken
to prevent
any dust or
iron filings
from getting
into and adhering
to the magnet.
Also
avoid
dropping
the
turntable
platter
onto
a
hard
surface,
as
this
may break
the magnet.

fingers,
so
that

Turn the balance weight forward to set the stylus pressure ring
to the proper stylus pressure of which you use.
NOTE
If the weight of the cartridge is over 8.5g, mount the auxiliary
weight to the rear shaft of the tonearm.

@ APPLY TWO OR THREE DROPS OF OIL TO THE MOTOR SHAFT
Disconnect the AC power plug and remove the turntable platter.
Lubricate two or three drops of oil to the turntable shat.
It is sufficient to lubricate the set once ater approximately 2000
hours of use.
This period is much longer than the ordinary motors, so do not
apply
too
much
oil,
nor
more
frequent
than
neccessary.
NOTE
Never use any other type of oil
The bearing parts of this set are designed with an ultra-precise
finish to prevent the generation of "WOW and FILUTTER”
A special oil has been used to maintain the high performance
jency of this set by forming a uniform film of oil over the
parts. For this reason, use only the oil included with this set for
its lubrication

10 FEATURES
(TURNTABLE SECTION)
@ TURNTABLE PLATTER ITSELF THE ROTOR OF THE MOTOR
The direct drive principle innovated by TECHNICS, which has
altered the course of turntable development, has now been car-
ried a step further. Not only does the SL-1300 feature automatic
player system, but it incorporates an ingenious redesign of the
direct drive motor itself.
The result is to connect the motor to the turntable platter directly,
of course, there is no reduction or transmission mechanism
such as a belt or idler.
The turntable platter itself is part of the motor.
In addition, the motor rotates at the same speed of the records.
Wear of parts is, therefore, reduced to the extreme minimum,
and high performance can be maintained.
Thus, there is no" WOW and FLUTTER" caused by a transmission
mechanism. There is no vibration because this motor has no
high
speed
rotation
mechanism.
The
rumble
is
extremely
low.
@NO EFFECT FROM FLUCTUATIONS OF THE POWER SUPPLY
FREQUENCY
Since the motor is the OC brushless motor, the rotation speed
does not depend on the power supply frequency.
And,
the
motor
power
consumption
is
only
0.1
W,
which
is
less
than
1/100th
that
of
a
conventional
AC
motor,
theretore,
there
is
no
effect
from
electro
magnetic
vibration.
@ ELECTRONIC STABILIZATION CONTROL
This
set
includes
special
circuitry
to
stabilize
the
speed
electri-
cally. Speed stability is extremely good.

@
SMOOTH,
FEATHER-TOUCH
MECHANISM,
IN
COMBINATION
WITH
PRECISION
PARTS
AND
INGENIOUS
CONSTRUCTION
The
automatic
mechanism
uses
precision
molded
plastic
parts,
in order
to avoid
the
noise
caused
by automatic
operation.
In
addition,
each
operation
knob
is
finished
precisely,
so
it
can
be operated
by a feather
touch.
‘And, there is no skipping
or skating
caused
by operation.
@EASY-VIEW STROBO
‘Two sets of strobo dots appear on the tapered rim for 33-1/3 and
45 r.p.m. at both 50 and 60 Hz synchronization, with either type of
AC source. The prism strobo illuminator lights when switch is on,
thus serving as a pilot lamp.
The combination of prism lamp and tapered strobo rim results in
easy viewing from any position.
@ ALUMINIUM DIECAST BASE
The appearance of the SL-1300 is enhanced by the attractively
styled die-cast aluminium base and compact finish.
(6)
@
EFFICIENT,
LOW-POWER
OPERATION
The motor power consumption is only 0.1 W and total power
consumption
is
less
than
4
W.
(While
automatic
mechanism
is
operating is 6.5W)
This is most important in terms of longer life and reliability.
That
is
more
than
the
saving
of
a
few
pennies
of
electrical
power,
but
means
less heat,
less
vibration,
less
stress
on
the
control
circuitry and less evaporation of lubricants.
The
result
is
not
merely
longer
motor
life,
which
may
be
a-
chieved
in
other
direct
drive
designs,
but
longer
life
of
the
entire
component

@
HIGH
QUALITY
UNIVERSAL
TONEARM
This
tonearm
is
especially
designed
for
the
SL-1300,
using
four
pairs
of
pivot
bearings
to
enhance
the
rotational
sensitivity
of
the
gimbal-suspended
type.
Thus
it
can
accept
any
cartridges,
stylus
pressure
of
which
is
at
0.25
gram.
@ SIMPLE AND EASY STRUCTURE OF THE HEAD SHELL
The
head
shell
is
finished
of
die-cast
aluminium
to
prevent
vibration.
‘The
structure
of
this
shell
is
simple,
so
that
the
installation
of
the
cartridge
and
the
adjustment
of
the
overhang
are
easy
and
fool-
proot.
@ LOW-CAPACITANCE PHONO CABLES
High-frequency
audio
losses
are
eliminated
and
discrete
4-chan-
nel
(CD-4)
records
can
be
played
through
a
suitable
cartridge
with no deterioration in carrier frequencies.
@ FEATHER-TOUCH CUEING
Feather-touch
cueing
is
viscous-damped
in
both
directions
for
gentle descent and ascent.
The tonearm will be set down exactly on the groove you desired,
thus protecting the stylus tip from damage.
@EASY ADJUSTMENT OF STYLUS PRESSURE
The
stylus
pressure
adjustment
is
easy
because
of
helical
type
‘of
movement,
just
turning
the
balance
weight
can
adjust
the
stylus pressure accurately.

By precision design, the inside force is canceled accurately.
