PARTS IDENTIFICATION
OPERATION AND FUNCTION OF CONTROLS

(TURNTABLE SECTION)
030109 (See Fig.1- 0)

This unit uses a direct drive motor. Therefore, the rotor, which is the
rotating part of the moxor,is connected directly to the turntable platter.
The spindle of the motor and the shaft of the turntable platter are the
same. For this reason, to maintain the high performance described in
the specifications. it is not desirable to apply a large amount of ex-
ternal force to the rotor and the spindle of the motor. The rotor is,
therefore. clamped securely to protect the delicate and important pans
during transportation.

Be sure to remove these fittings 9 carefully, and save them for future
use, as when, for example, the player must again be transported
NOTE

The rotor of the motor is constructed so that it cannot be removed in
order to maintain its high performance for a long time.

Do not attempt to remove the removal prevention fitting @ for the
rotor.

GPILOT LAMP (See Fig.1. 0)

QPOWER SWITCH/SPEED SELECTOR (See Fig.1- 0I
Set the speed selector" to the desired position (33 or 45, depending
upon the speed of the record to be played). The pilot lamp will be
lighted. The turntable platter will not rotate unless you push the
START" button.

QSTART BUTTON (See Fig.1- 0 I
Push the "START" button and the turntable platter will rotate._
Starting rotation power is large with complete stability of speed
reached within one-half rotation at 31/3 r.p.m.

OSTOP BUTTON (See Fig.1- OI
Push the "STOP" button when you want to stop the rotation. The
turntable platter will continue to rotate for a short time because of
its large inertial force.

OVARIABLE PITCH CONTROLS (See Fig.1. OI
Adjust the "variable pitch controls" if necessary. These are designed
to provide adjustment of the selected speed by 10% range
Select the speed of the turntable platter by setting the "speed selector"
to the desired position. The rotating turntable platter when illuminated
by conventional fluorescent lamp or by neon lamp may show move-
ment of the marks on the strobo disc. if so, adjust the "variable pitch
controls" until the strobo marks are stationary.
After the necessary adjustment has been made. the speed will not
change and readjustment will not be necessary.
The strobo marks molded around the turntable platter are used to
check the correct speed of rotation for 50 Hz (European), and 60 Hz
(U.S.A.l. Adjust its rotation according to the strobo label.

OSTROBO MARKS (See Fig.1- 0 I

ll, for any reason, the adjustment cannot be successfully made, use
a (-I tip screwdriver to adjust the appropriate speed adjustment screws
(33 or 45) located beneath the turntable platter.

Turning the speed adjustment screws to the right or left will increase
or decrease the speed respectively.

OAC OUTLET @(See Fig.1- 0 I

This one is designed with a view to luture use. that is for your special
convenience such as for neon lamp or stylus illumination light.

OSPECIAL OIL (See Fig.1- 0 l
The bearing parts of this set are designed with an ultra-prescise finish
to prevent the generation of "Wow and Flutter".
A special oil has been used to maintain the high-performance efficiency
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.
Even if there is oil leakage around the oil hole or the rotor, caused
during transportation, it will not effect the performance.
Before use, apply about 2 drops of oil into the oil hole.
To lubricate, open the tip of the vessel with a needle. After lubricating,
cover the vessel with the cap to prevent the leakage of oil.
Never use any other type of oil. To lubricate, remove the turntable
platter and apply about 2 drops of oil into the oil hole.
It is sufficient to lubricate the set once after approximately 2,000 hours
of use.
Two thousand hours are equivalent to 5-1/2 years. if the set is used
one hour a day, or to 8 months if used 8 hours a day.
This period is much longer than has been necessary on previous. con-
ventional motors. Do not apply too much oil. nor more often than
necessary.

FEATURES
(TURNTABLE SECTION)

035 CM I13-25/32") ULTRA-LARGE DIAMETER
TURNTABLE PLATER

35cm (1325/32) ultra~large diameter. and 2kg (4.4 lb) heavy weight
turntable platter has an inertial moment of 320 kg-cm2 (109.5 lb-inz)
and the turntable platter has been dynamically balanced.

Around the turntable platter are strobo marks which are used to
check its speed.

ODIRECT DRIVE MOTOR

There is no "wow" or flutter" caused by transmission mechanism.
There is no vibration because this motor has no high-speed rotation
mechanism. The rumble is extremely low.

OELECTRONIC COMMUTATOR BRUSHLESS DC MOTOR
The DC motor is not affected by fluctuations of the power supply
frequency. Starting rotation power is large, with complete stability
of speed reached within one-half rotation at 33-1/3 r.p.m. Since there
is no electromagnetic hum. the signal to noise ratio (rumble) is ex-
cellent. And, because the motor includes an electronic commutator,
starting is perfectly accurate, There is. therefore, no speed instability
or brush deterioration as is often noted in brush commutators, no
pulse noise generated by brush sparking and no sound caused by
rubbing of brushes.

OROTATION OF THE TURNTABLE PLATTER CAN BE
STOPPED AT ANY TIME

This is a feature which is not found in players which have speed
reduction and transmissions devices such as a belt or idler.

If such stopping is attempted on ordinary players. the belt or idler will
soon deteriorate and efficiency soon becomes poor. In this player
system. such stopping causes no problem other than a slight increase
of the motor current, which is not really a problem.

OELECTRONIC STABILIZATION CONTROL
Because this set includes special circuitry to stabilize the speed
electrically. speed stability is extremely good.

OELECTRICAL SPEED CHANGE
There is no mechanism to change the position of the belt or idler.
There is. therefore, no wow" or unwanted speed change.

ONO EFFECT FROM FLUCTUATIONS OF POWER SUPPLY
FREQUENCY OR VOLTAGE
Since the motor is the DC type, the rotation speed does not depend
on the power supply frequency. And, because a DC-stabilizer is used.
the set is not affected ,by changes of the power supply voltage. even
if the fluctuation is large.

OSEMI-PERMANENT HIGH PERFORMANCE
Unlike previous players, there is no reduction or transmission mecha-
nism, such as a belt or idler.
The motor rotates the turntable platter directly. at an ultanlow speed.
Wear of parts is therefore, reduced to the extreme minimum and high
performance efficiency can be maintained semi-permanently.

OPOWER CONSUMPTION IS 1/100TH THAT OF
ORDINARY MOTORS
Motor power consumption is only 0.1W, which is less than lllOOth
that of a conventional AC motor. (There is a power consumption of
about 4W, in addition to the drive, on other electronic circuitry).

(TONEARM SECTION)

ODETACHABLE ARM PANEL
Arm panel can be detached by unscrewing just in case you might
decide to change the tonwm.

OEASY BALANCING AND STYLUS PRESSURE CONTROL
By a smooth rack-andpinion type movement, the balance weight can
be adjusted easily. After adjusting the balance. pull the outside of the
stulys pressure knob outward. and the scale will be reset automatically
to the zero position. Now you can add the amount of stylus pressure
you desire by directly reading the scale.

OFEATURE-TOUCH CUEING
Feather-touch cueing is viscousdamped in both directions for gentle
decent and ascent. The tonearm will be set down exactly on the
spot you desire.
