6. CIRCUIT DESCRIPTIONS
6.1 SIGNAL PATHS
Recording Mode
The signal from MIC is first amplified to the
fixed level by the MIC amplifier (HA12005) and
then applied via the MIC position of the S3; MIC/
LINE selector (MIC position switched in auto-
matically when microphone plugged into the MIC
jack) to the VR1; INPUT level control, flat ampli-
fier (HA12005), MPX filter, and DOLBY NR
circuit,
The signal from the LINE INPUT is passed via
53 to the INPUT level control, flat amplifier,
MPX filter, and DOLBY NR circuit. After the
frequency response has been equalized by the
recording amplifier (Q104) equalizer circuit
(according to the type of tape being employed),
the output signal is applied to the recording head.

The signal from the playback head is first equal-
ized in the playback equalizer amplifier (HA12005)
according to the type of tape being employed, and
then it is amplified to the fixed level. The output
of DOLBY NR is then applied to the LINE OUT-
PUT via the REC/PB switch (located HA12005)
and MUTE switch (located HA12006).

6.2 CONTROL CIRCUIT
The control circuit employed in this tape deck
IC302(BA843) for use in the electronic control of
the switching. See Fig. 6-2 and Fig. 6-3 for the
corresponding pin arrangement and input/output
truth table.
Vee OFF OFAST ORW Orey Ora OREC
Fig. 6-2 Pin arangement of BA843
For 1.5 ~ 2.5 seconds after the power has been
turned on, Q309 is ON (until charge-amp C322
has completed). Since IC302 (2 pin) is at a LOW
level, it is in a STOP status and no key is operable.
Play Operation
1. When play switch S4 is pressed ON, IC302
(12 pin) goes to a high level (hereafter called H
level). This causes +B to flow through R343,
R344, and Q312, turning Q312 ON.
2. The pinch solenoid (P.S.) is activated starting
play operation.
CT T-200
Record Operation
1. Loading a cassette with an erase prevention
detector (AR SW S10 is on no hole side),
press play switch S4 and record switch S9
simultaneously.
2. IC302 (12 pin) and (10 pin) go to H level,
current flows from R319 to Q303 and Q303
comes ON. IC301 (HA12006) (2 pin) goes to
a low level (hereafter called L level).
3. As IC301 (2 pin) goes to L level, IC301 (6 pin)
and (16 pin) go to H level and the head goes to
a record status.
4. At the same time, as was noted earlier, IC302
(10 pin) goes to H level and the bias oscillator
comes ON,
5. When a cassette without an erase prevention
detector, AR SW is on the hole side, IC302
(9 pin) is shorted to ground causing IC302
(10 pin) not to go to H level, and preventing
recording.
FF, REW, Operation
1. Pressing FF switch S6 to ON causes IC302 (15
pin) to go to H level. +B flows through R337,
R338, and Q310 and Q310 comes ON.
2. FFS (Fast Forward Solenoid) becomes operat-
ive and FF operation begins.
3. Rewind operation is essentially the same as FF.
Pause Operation
When either in the play or record mode, press-
ing the pause switch $8 to ON causes IC302 (12
pin) to go from an H level to an L level. This
causes Q312 to go OFF, releasing the pinch sole-
noid and temporarily stopping play or record.

CT T-200
Auto-stop Circuit
When the tape has reached the end of its travel,
the control IC goes into the STOP mode, stopping
the mechanism. A photo-interruptor is used as the
tape travel sensor. It is connected by belt to the
take-up reel and uses fan blades to intercept the
path of light.
1. During tape travel, the turning of the fan
causes the photo-interruptor to generate a
pulse signal. This causes Q304 to cycle ON-
OFF and C321 repeats a charge-discharge
cycle.
2. When tape travel stops, the signal from the
photo-interruptor is lost, and Q304 stops
lts switching operation. +B charges C321 by
route of R326 — R327 — C321. Along with
the charging of C321, the potential at the base
of Q305 rises and Q305 goes OFF. When
Q305 goes OFF, Q306 goes ON, IC302 goes to
STOP mode and operation ceases. This circuit
is only effective during PLAY, FF and REW
operations.

6.3 MUTING CIRCUIT
This set uses an IC-HA12006 for line output
muting. This IC (IC301) is only effective in mut-
ing when REC input (2 pin) is at H level at the
same time PLAY input (15 pin) is at L level.
[IC301 (12 pin) gose L level]
FF/REW/STOP
At FF, REW, and STOP, IC302 (10 pin) and
(12 pin) are both at L level. When IC302 (12 pin)
is at L level, IC301 (15 pin) is also at L level, and
when IC302 (10 pin) is at L level, Q303 is OFF.
This causes 1C302 (2 pin) to go to H level, muting
LINE OUT, and current to flow from 1C301 (2
pin) through the route D301 > R154 > Q1083,
muting the record amp.
Turning the Power Switch ON
When the power switch is turned ÓN, as was
mentioned previously, the set is in a STOP status
for 1.5 ~ 2.5 seconds after the power is turned
on, and LINE OUT and the record amp is muted.
Also current flows through the route C334 > R360
> R161 > Q106 and Q106 goes to ON. The meter
is muted until C334 is charged up and Q106 goes
to OFF.
Going from STOP Status to PLAY
When going from STOP to PLAY, IC302 (12
pin) goes from L level to H level and through
C315 — R349 — D304, sends current to IC301
(1 pin), muting LINE OUT. Muting continues
unitl C315 is charged up. (approx. 0.6 sec.)

7.1
PINCH ROLLER PRESSURE ADJUSTMENT
1. Put the tape deck into the playback mode.
2. Gently push against the pinch roller arm with
the tension gauge (Part No. GGK-047) and
separate the pinch roller slightly from the
capstan.
3. Then the pinch roller back onto the capstan,
and read the value when the pinch roller starts
to rotate. If the reading fails to lie within
350g ~ 550g, replace the pinch roller pressure
spring (Part No. RBH-760).

7.2 REEL BASE TORQUE ADJUSTMENT
Prior to adjustment
Clean the both reel base, the capstan and the
pinch roller with an alcohol moistened swab.
Adjustment
Measure the torque with the torque meter
during playback, fast forward (FF) and rewind
(REW) modes. The measured values should
normally lie within the allowable ranges listed in
the table 1.
If the measured values lie outside the relevant
ranges, replace the TU (take-up) reel base assembly
and/or supply reel base assembly (Part No. RXB-
377), or driving arm full assembly (Part No. RXB-
376).

7.3 TAPE SPEED ADJUSTMENT
1. Connect the frequency counter to the OUT-
PUT terminals (to pin code).
2. Playback the 3kHz portion of the STD-301
test tape. At the beginning, the frequency
should be lie within the 2995Hz ~ 3010Hz
range, and may be adjusted by turning the
semi-fixed resistor located in the capstan motor
adjustment hole as shown in Fig. 7-2.
Tape speed is increased by turning the semi-fixed resistor
clockwise, and decreased by turning counter-clockwise.

74 RECDETECTOR SWITCH ADJUSTMENT
Adjust the tang (=>) shown in Fig. 7-3 by the
arrow to a position where when a cassette with an
erase prevention detector is loaded into the holder,
the lever switch is ON, and when a cassette without
the detector is loaded, the switch is OFF.

1. Put the deck into FF mode.
2. Loosen screws @ and adjust the FF solenoid
mounting position so that the square hole of
the reel base full assembly is flush against the
boss of the driving arm full assembly (i.e. O
separation) as shown in Fig. 7-4.

Precaution
1.
2.
Mechanical adjustment should be completed.
Clean the following parts with an alcohol
moistened swab: Record/Playback head, Pinch
roller, Erase head, Rubber belts and Capstan.
Demagnetize record/playback head with a head
demagnetizer.
Do not use magnetized screwdriver for adjust-
ments.
Adjustments and measurements should be per-
formed for both L-ch and R-ch with rated
power supply voltage.
Adjustments should be performed in the order
given in this service manual. Altering the order
can hinder proper adjustments, resulting in loss
of performance.
Level during measurements are based on OdBv=
1V. Connect a 50k 2 dummy resistor across the
OUTPUT terminals.
Let the CT-200 warm up (aging) for a few
minutes before proceeding with the adjust-
ment.
Set the DOLBY NR switch OFF unless direct-
ed otherwise,
