SOME UNIQUE FEATURES:
aFM front - end employing a field effect
transistor to hear more stations more clearly
olntegrated circuit (lC) employed in FM tuner
assures outstanding capture ratio with high
reliability.
oMultiplex circuitry (MPX) for maximum
channel separation
oUnique muting circuit permits the easiest
tuning control
oHigh performance single ended push-pull
(SEPP) output stage eliminates audio
transformers and provides large output with
true frequency fidelity
OFull complement of inputs and outputs
oElectronic switch fully protects
precious power transistors the
By the use of FET (field effect transistor) in the FM radio frequency amplifier
stage, design of nearly perfect FlVl front-end was achieved-free from cross
modulation, free from drift, with better sensitivity, lower inherent noise, and
high spurious rejection ratio.
ln the FM intermediate frequency amplifier stage, integrated circuits are employed,
resulting in an entirely different outstanding performance from that of lFstages
hitherto designed, especially in the limiter characteristic and the capture ratio.
The accurate electronic switching circuitry is employed in the FM multiplex
demodulator, insuring maximum separation with excellent tonal quality.
The muting circuit provided in the FlVl tuner completely eliminates the FM
inter station noise whrch has hitherto been annoying the user in tuning.
The power amplif ier employs the high-performance single ended push- pull
circuitry in the output stage and the push,pull complementary circuitry in the
driver stage, completely eliminating the distortion rnherent transformers from
the audio stage. Tripple diffused mesa transistors are adopted as the power
transistors in the output stage for full-fidelity frequency response with large
audio output power and least harmonic distortion.
The inputs and outputs pr,ovided in the receiver include two pairs of pHONO
MAG inputs. When two turntables are connected to these inputs, the user
is able to switch from one turntable to the other any time at will. Also, two
pairs of ioudspeaker outputs are included for switching between, or for per-
mitting the simultaneous use of, two loudspeakers.
The electronic switchrng circuitry employed in the power supply completely protects
expensive power transistors even when the loudspeaker leads are shorted while
the receiver un,L is in use
INSTALLATION
As this receiver is sully transistorized, desirable places to install
it are as follows:
OPlaces airy and free from humidity and dust. Avoid insta ling
on close, low-ceiling shelves.
OPlaces not directly exposed to the sun ray.
OPlaces not close to heat-emitting objects such as heaters and
stoves.
LINE VOLTAGE SELECTION AND FUSE
Switching Line Voltage Setting and Fuse
In order to remove the fuse, turn the fuse cap located on the
line voltage selector switch in the direction indicated by an arrow.
Then remove the fuse plug from the unit. Put the fuse plug
back so that the proper line voltage marktng can be seen thru
the cut on the edge of the plug.
Whenever the set position of the selector swttch is changed,
check the rating of the fuse. A 1.5-ampere fuse is to be used
for either 220\l or 24OV operation and a 3-ampere fuse for
any of 110V, 117V, or 130V operation. lf the rating of the
fuse is proper, install the fuse on ihe fuse cap.
OPlaces where there is as little vibration as possible and where
the surface is level.
The optimum stereophonic listening position is across the room
from the speakers, sornewhere close to the midpoini between
the right and leit speaker systems.

OReplacing of Fuse
When the fuse is blown off, remove the fuse cap and replace
the fuse with a new one.

Antenna
and Ground Connections
AM antenna
OThe ferrite loopstick antenna (181 mounted on the rear of the
receiver will provide satisfactory reception of local stations
with strong signals. Because the loopstick antenna has di
rective properties, its direction may be adjusted for the best
reception while listening to a statron.
Fig. 6
Olf noise is strong in your area and the adjustment of the
loopstick antenna direction does not improve the situation, the
furnished AM lead antenna may be laid on the wall or on
other standing object as high as possible, and one end of the
antenna lead should be connected to the AM antenna terminal
(22). lf ihe furnished antenna dose not help, an outdoor AM
antenna may need to be set up. In this case, the antenna
lead should also be connected to the Alvl antenna terminal
(22)
FM Antenna
Olf the receiver is situated in regions close to the transmitting
site or is placed in a wooden building, the furnished simple
indoor T-shaped antenna will provide satisfactory results. ln
this case, the 2 wires of the twin leads from the antenna
should be connected to the Fl\1 antenna terminals (24) and
the horizontal element of the T-section should be extended
and positioned for the best reception while listening to an FM
station. Then, the antenna should be secured to the wall or
to any support.
Oln regions where the furnished indoorT-shaped antenna provides
poor results such as many noises or poor channel separation,
an outdoor FM antenna may be required. ln this case, the leads
from the outdoor antenna should also be connected to the
FM antenna terminals (24).
For information about the outdoor FM antenna, consuit a
TV shop in your area.
OG rou nd
ln some area, the use of a proper ground reduces noise sig-
nificantly. The lead from an appropriate grounding electrode
such as a water pipe or a ground rod, is connected to GROUND
TERIVIINAL (23).
Loudspeaker Connections
OTwo loudspeaker systems, the main and the extra , (the left
and right channel loudspeakers per system or four loudspeakers
in total) may be connected to the receiver. Note, however, that
the impedance of each channel loudspeaker must be larger
than four ohms when two loudspeaker systems are connected
to the receiverl
OAs shown in Fig. 8, the loudspeaker leads are connected to
the speaker plug furnished with this receiver. In this case, be
sure that the positive loudspeaker lead is connected to the
positive terminal on the plug with reference to Fig. g .

The outpui leads from the iape player or deck which is not
equipped with the playback preamplifier (equalizer) are connected
to the TAPE HD input jacks (25). The upper input jack is for
the left channel and the lower is for the right channel. When
a monaural tape deck is used, its output lead may be connected
either to the upper input jack or to the lower input jack.
2. The second loudspeaker system is connected to the EXTRA
LOUDSPEAKER TERtvttNALS(3S)and(39)in the simitar manner
described in the preceding paragraph; the right channel loud-
speaker ts connected to the terminals(3g)and the Ieft channel
loudspeaker to the terminals(39).
Turntable connections
Two record players with a magnetic type pickup cartridge and
one record player with either a ceramic or a crystal type cartridge
may be connected to this receiver at a time, and an optional
record player can be selected for operation.
Magnetic pickup turntable connections
1. When using a turntable equipped with a magnetic iype pick-
up cartridge, the output leads should be connected to the
PHONO 1 input jacks (26). The upper input jack is for the
left channel and the lower s for the right channel. When a
monaural turntable is used, it does not matter which of the
two inputs the output cable is connected to.
2. When two turntables are used, the first set is connected to
the PH0NO 1 input jacks as described herein above, and
the second set is likewise connected to the PH0NO 2 input
iacks (27).
Geramiclcrystal pickup turntable connections
When using a turntable equipped with either a ceramic or a crystal
pickup cartridge, the output ieads are connected to the pHONO
CER input lacks (29). The upper input jack is for the left
channel and the lower is for the right channel. When a
monaural turntable rs used, the output cable may be connected
to either the upper input.lack or the lower.
Tape recorder connections
For making recordings
The signals of the program material to be recorded are taken
from the TAPE REC output jacks (32) and are connected to
the LINE INPUTS of the tape recorder. The upper jack is for
the left channet and the lower jack is for the right channel. When
usrng a monaural tape recorder, the signal may be derived from
either of the two output jacks.
OThe srgnals available at the TApE REC output jacks(32) are
not controlled by any of the controls of the receiver, namely,
VOLUME (10), BASS (7), and TREBLE (8) Therefore, ad-
justment of the recording level must be made with the con-
trols of the tape recorder.
Tape playback and tape monitor connections
The losram material to be reproduced through the receiver rs
derived from the LINE 0UTPUTS (the playback outputs or the
l\4ONITOR ouiputs) of the tape recorder and is connected to the
TAPE lvl0N input jacks (31) of the receiver. The upper input
jack is for the left channel and the lower lack is for the right
channel. When using a monaural tape recorder, its output cable
is connected to either of the two input jacks of the receiver.
aThe program signal fed to the TApE MON input iacks (31) can
be controlled by the controls of the receiver, such as V0LUI\4E,
BASS, and TREBLt.

Noise: There are a variety of noises relating to the operation
of a hi f i unit. These are generally divided into two types; 0)
the unit is sick (a transistor or part is deieriorated) and 12) an
external source of noise is giving noise to the unit.
When a hi-fi unit produces an unpleasant noise, it is frequentiy
judged that the unit is sick, but a statistical record indicates
that the majority of noises produced in a hi,fi acoustic unit is
resulted from external sources of noise. Due to the inherent
