Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ! OR DOTTED
LINE WITH MARK ! ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-
LISHED BY SONY.

SECTION 3
MECHANICAL ADJUSTMENTS
PRECAUTION
1. Clean the following parts with a denatured alcohol-moistened
swab:
record/playback/erase head pinch roller
rubber belts capstan
idler
2. Demagnetize the record/playback head with a head demagne-
tizer.
(Head demagnetizer do not approach for the erase head.)
3. Do not use a magnetized screwdriver for the adjustment.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
• Torque Measurement
Record/Playback Head Height/Declination Adjustment
Procedures:
1. Test cassette: CQ-009C
2. Insert the mirror cassette and put the unit in record/Playback
mode.
1) Height Adjustment:
Check to see if the tape is curling at the tape guide of the head.
If it is curling, tighten screws A, B and C, respectively by
the same angle, moving the head so that it remains at the same
angle throughout the procedure. If it curls on the bottom side
of the mirror cassette (actually the inner side), tighten all the
screws equally; but loosen them if the tape begins to curl on
the top side. (outer side.)
Mode Torque Meter Meter Reading
Forward CQ-102C 30 to 65 g•cm
(0.42 to 0.90 oz•inch)
Forward
back CQ-102C 1 to 6 g•cm
tension (0.014 to 0.08 oz•inch)
FF/REW CQ-201B 70 to 120 g•cm
(0.98 to 1.66 oz•inch)
2) Declination Adjustment:
While in the record/playback position, set the back tension to
0 (wind the supply reel with something thin like a pencil in a
counterclockwise direction) and make sure there is no curling
or shifting (shifting up/shifting down) at the guide of the
record/playback head.
Because shifting can only occur due to a difference in the width
of the tape and that of the tape guides (curling will otherwise
occur), it is necessary to pay close attention since it can be
easily overlooked.
When there is a shift, tighten screws B and C equally and
change the declination of the head. If the tape is shifting up,
tighten the screws, and if it is shifting down, loosen them.
Repeat the adjustments in steps 1) to 2) and fine adjust the
height and the declination.

SECTION 4
ELECTRICAL ADJUSTMENTS
Note: The adjustment should be performed in the order given in the ser-
vice manual. As a rule, adjustments about playback should be per-
formed before those about recording.
The adjustments should be performed before for both L-CH and R-
CH.
• Switches and controls should be set as follows unless otherwise
specified.
DOLBY NR, MPX FILTER switch: OFF
MONITOR switch: Tape
• Standard Record:
Deliver the standard input signal level to the input jack and set
the REC LEVEL control to obtain the standard output signal
level.
– Record Mode –

Tape Speed Adjustment
Procedure:
Mode: playback
1. Set to FWD playback mode.
2. Adjust RV71 so that the frequency counter reading becomes
3,000±90 Hz.
3. Frequency difference between the beginning and the end of
the tape should be within 3%.

Playback Level Adjustment
Procedure:
Mode: playback
Adjust RV121 (L-CH) and RV221 (R-CH) so that the reading on
level meter meets the adjustment limits below.
Adjustment Limits:
LINE OUT level: –7.7±0.5 dB (0.301 to 0.338 V)
Level difference between channels: within 0.5 dB
Check that the LINE OUT level does not change even if Playback
and Stop operation is repeated several times.
