FAST-FORWARD MECHANISM
Turn the FAST FWD-REWIND knob {A) to "FAST FWD”
position, and fhe cam (B) under the knob pushes up fhe
Lever (C}. The Idler (D) moves into the space between
the Plastic Roller (F) above the Take-Up Reel Spindle and
the upper part of the rotating motor drive bushing tc
transmit the motor rotation to the take-up reel spindle.
At the same time, the Brake Band (H) and Brake Roller (1)
come off ine reel spindle to free ihe Supply Reel Spindle
(G), thereby allowing fast winding of the tape onto the
take-up reel.

REWIND MECHANISM
Turn the FAST FWD-REWIND knob (A) to "REWIND”
position, and the cam (B) under the knob pushes the Lever
(C) up. The Idler (D} moves into the space between the
upper part of the rotating Motor drive bushing (B) and
the Intermediate Pulley (F! to transmit the high-speed
rotation of the motor through the intermediate puiley io
the Supply Reel Spindle |G). At the same tim>, Brake
roller (H) and Brake Band (1) come off the reel spindle to
free the take-up reel spindle (J), thereby rewinding the
taps into the supply reel at 2 fast speed.

STOP CONTROL
Push the stop lever to “STOP” position, Brake Roller
(A), and Brake Band 1B) depress reel spindles to stop rota-
tion of the reel spindles.
As brake rubber depresses the plastic rollers under
the reel spindles, no friction works on the tane itself.

For “Fast-forwa:a’, or “Rewind”, the Corkscrew lever 'H)
works to push back the "FAST FWD, REWIND” knob to
the “Stop” position before stopping itself.
When the Automatic Cut-Off Switch is moved to “CUT
OFF" position, the Shut-Off lever (J) moves to the arrow-
mark direction to cut the power circuit, thereby depres-
sing the attached Micro Switch (K) to shut off the current.

ASSEMBLY
A
felt
clutch
material
is
attached
to
the
bottom
side
of
the
reel
table
base
plate
so
that
recording
tape
will
not
be
siretched
during
fast
forwarding
operation
due
to
excessive
tension.
To
check
the
amount
of
friction
of
this
part,
place
onto
the
take-up
reel
table
a
5-inch
reel
with
recording
tape
wound
by
60

in
diameter,
and
gently
pull
the
end
of
tape
upward
using
a
spring
scale.
Adjust
the
conical

so
that
the
amount
of

at
this

will
be
kept
between
400
to
500
grams.
Another
felt

is
attached
to
the
take-up

Itis
used
to
provide
proper
slipping

tion
during

The
procedure
for
checking
friction
of
this
part
is
same
as
the
foregoing,
and
between
120
and
200
grams
of
friction
will
provide
the
bert
result.
Adjust
the
star-shaped
spring
immediate
below
the

When
the

the
amount
of

reduced
and
will
become
10

ADJUSTMENT
OF
AMPLIFIER
1, ADJUSTMENT OF RECORDING BIAS
FREQUENCY
Recording/erasing bias frequency has been set at 60 KC
plus or minus 5 KC before shipment. It is decided by
inductance of the oscillator coil (part 3 OSC 60) and its
resonant capacitor (part % C-22). To measure recording
bias frequency, insert a 10 or 100 ohm resistor in series
to the record/play head and connect vertical input
terminals cf an oscilloscope as shown in the Fig. 13.
Another testing instrament to be prepared is an audic
frequency oscillator and its output should be connected
to horizontal input terminals of the oscilloscope. Vary
frequency being generated by the audio frequency osci-
lator around 60 KC, and set the oscillator at the point
where a lissajous figure appears on the oscilloscope. The
recording bias frequency now corresponds to the reading
of the oscillator. Check oscillator coil, C-22, C-27 and
bias head if recording bies frequency measured is not
within 60 KC plus or minus 5 KC.
2. ADJUSTMENT OF RECORDING BIAS
VOLTAGE
A proper recording bias voltage differs on each head
from 130 to 230 volts A.'c., and it is stammed on the
mounting bracket of tape head assembly. To measure
recording bias voltage, connect a V. T. V. M. (Vacuum
T243 Volt Mete:) to the record/play head as shown in
the Fig. 14. Check C-21, C-27 and bias head if record-
ing bias voltage does not meet to the above-mentioned
specification after adjusting C-27, a 100 pf variable
capacitor.
3. ADJUSTMENT OF ERASING BIAS VOLTAGE
A proper erasing bias voltage is decided automatically
as recording bias voltage is set. The erasing bias volta-
ge, however, should always be more than 170 volts A.C.
To measure erasing bias voltage, connect a V.T. V. M. to
the erase head as shown in the Fig. 15. Check C-21
‘(1000 pt mica capacitor) and erase head if erasing bias
voltage measured is lower than 170 volts A.C.
4. ADJUSTMENT OF RECORDING LEVEL
A basic recording level, usually referred to as “O VU",
a set at the poirt where current of 20 wA+10% flows to
the recording head at 1000 cycles. The VU meter indi-
cates 0 VU +2 VU when a signal of 55 db +5 db at the
microphone jack or —15 db +5 db at the line input jack
a given with the volume control set at its maximum.
Adjustment of recording level can be accomplished by
varying sensitivity of VU meter, however, it is not neces-
sary to make in a field of service as all VU meters have
correctly been calibrated at factory before shipment.
See Fig. 16 for details.
NOTE: Make sure to stop oscillation by disconnecting
the oscillator coil $ CSC 60 at the points marked
"RP" and "G" prior to measurement of recording
level.
