PRECAUTION
1.1IMPORTANT SAFETY PRECAUTIONS
1.1.1 Product Safety Notice
Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by
replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by a on schematics and in parts lists. Use of a substitute
replacement that does not have the same safety characteristics
as the recommended replacement part might create shock, fire,
and/or other hazards. The Product's Safety is under review continuously and new instructions are issued whenever appropriate.
Prior to shipment from the factory, our products are carefully inspected to confirm with the recognized product safety and electrical codes of the countries in which they are to be sold.
However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
1.1.2 Precautions during Servicing
(1) Parts identified by the symbol are critical for safety. Re-
place only with part number specified.
(2) In addition to safety, other parts and assemblies are spec-
ified for conformance with regulations applying to spurious
radiation. These must also be replaced only with specified
replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
(3) Use specified internal wiring. Note especially:
a) Wires covered with PVC tubing
b) Double insulated wires
c) High voltage leads
(4) Use specified insulating materials for hazardous live parts.
Note especially:
a) Insulation tape
b) PVC tubing
c) Spacers
d) Insulators for transistors
(5) When replacing AC primary side components (transform-
ers, power cord, etc.), wrap ends of wires securely about
the terminals before soldering.
(6) Observe that the wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors,
etc.).
(7) Check that replaced wires do not contact sharp edges or
pointed parts.
(8) When a power cord has been replaced, check that 5 - 6 kg
of force in any direction will not loosen it.
(9) Also check areas surrounding repaired locations.
(10) Be careful that foreign objects (screws, solder droplets,
etc.) do not remain inside the set.
(11) Crimp type wire connector
The power transformer uses crimp type connectors which
connect the power cord and the primary side of the transformer. When replacing the transformer, follow these steps
carefully and precisely to prevent shock hazards.
Replacement procedure
a) Remove the old connector by cutting the wires at a
point close to the connector.
Important: Do not re-use a connector. (Discard
it.)
b) Strip about 15 mm of the insulation from the ends of
the wires. If the wires are stranded, twist the strands
to avoid frayed conductors.
c) Align the lengths of the wires to be connected. Insert
the wires fully into the connector.
d) Use a crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to the complete closure
of the tool.
(12) When connecting or disconnecting the internal connectors,
first, disconnect the AC plug from the AC outlet.
(No.YD087)1-3
1.1.3 Safety Check after Servicing
Examine the area surrounding the repaired location for damage
or deterioration. Observe that screws, parts, and wires have
been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards.
1.1.3.1Clearance Distance
When replacing primary circuit components, confirm specified
clearance distance (d) and (d') between soldered terminals, and
between terminals and surrounding metallic parts. (See Fig.1)

1.1.3.2Leakage Current Test
Confirm the specified (or lower) leakage current between B
(earth ground, power cord plug prongs) and externally exposed
accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone
jacks, etc.) is lower than or equal to the specified value in the table below.
Measuring Method (Power ON) :
Insert load Z between B (earth ground, power cord plug
prongs) and exposed accessible parts. Use an AC voltmeter to
measure across the terminals of load Z. See Fig. 2 and the following table.

1.2.5 Instructions for Handling Semi-conductors
Electrostatic breakdown of the semi-conductors may occur due
to a potential difference caused by electrostatic charge during
unpacking or repair work.
1.2.5.1Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly ground-
ed to remove any static electricity that may be charged on the
body.
1.2.5.2Ground for Workbench
(1) Be sure to place a conductive sheet or copper plate with
proper grounding (1MΩ) on the workbench or other sur-
face, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semi-conductors with your clothing.

4.4.2.2X Value Alignment
Purpose:
To obtain maximum PB FM envelope signal at the preset position of the Tracking Control Circuit, align the Horizontal Position of the ACE Head.
Symptom of Misalignment:
If the Horizontal Position of the ACE Head is not properly
aligned, maximum PB FM envelope cannot be obtained at the
preset position of the Tracking Control Circuit.
(1) Connect the oscilloscope to TP301 (C-PB) and TP503
(CTL) on the Main CBA. Use TP504 (RF-SW) as a trigger.
(2) Playback the Gray Scale of the Alignment Tape
(FL6NS8) and confirm that the PB FM signal is present.
(3) Set the Tracking Control Circuit to the preset position by
pressing “PR +” button and then “” button on the unit.
(Refer to note on bottom of page 1-34.)
(4) Use the Flat Screwdriver so that the PB FM signal at
TP301 (C-PB) is maximum.(Fig. 6)

4.4.2.3Checking/Adjustment of Envelope Waveform
Purpose:
To achieve a satisfactory picture, adjust the Guide Rollers so
that the PB FM envelope becomes as flat as possible.
Symptom of Misalignment:
If the envelope output is poor, noise will appear in the picture.
The tracking will then lose precision and the playback picture
will be distorted by any slight variation of the Tracking Control
Circuit.
(1) Connect the oscilloscope to TP301 (C-PB) on the Main
CBA. Use TP504 (RF-SW) as a trigger.
(2) Playback the Gray Scale on the Alignment Tape(MHPE-L).
Set the Tracking Control Circuit to the preset position by
pressing “PR +” button and then VCR “” button on the
unit. Adjust the height of Guide Rollers [2] and [3](Fig. 3,
Page 1-33) watching the oscilloscope display so that the
envelope becomes as flat as possible. To do this adjustment, turn the top of the Guide Roller with the Guide Roller
Adj. Screwdriver.
(3) If the envelope is as shown in Fig. 7, adjust the height of
Guide Roller [2] (Refer to Fig. 3) so that the waveform looks
like the one shown in Fig. 9.
(4) If the envelope is as shown in Fig. 8, adjust the height of
Guide Roller [3] (Refer to Fig. 3) so that the waveform looks
like the one shown in Fig. 9.
(5) When Guide Rollers [2] and [3] (Refer to Fig. 3)are aligned
properly, there is no envelope drop either at the beginning
or end of track as shown in Fig. 9.
Fig.8
Dropping envelope level at the end of track.
Fig.9
Envelope is adjusted properly. (No envelope drop)
Fig.10
Note:
Upon completion of the adjustment of Guide Rollers [2] and [3]
(Refer to Fig. 3), check the X Value by pushing the “PR +”or
“PR -” buttons on the unit alternately, to check the symmetry
of the envelope. Check the number of pushes to ensure preset
position. The number of pushes of the “PR +” button on the unit
to achieve 1/2 level of envelope should match the number of
pushes of the “PR -” button on the unit from center. If required,
redo the “X Value Alignment.”
1-34 (No.YD087)
4.4.2.4Azimuth Alignment of Audio/Control/ Erase Head
Purpose:
To correct the Azimuth alignment so that the Audio/Control/
Erase Head meets tape tracks properly.
Symptom of Misalignment:
If the position of the Audio/Control/Erase Head is not properly
aligned, the Audio S/N Ratio or Frequency Response will be
poor.
(1) Connect the oscilloscope to the audio output jack on the
rear side of the deck.
(2) Playback the alignment tape (MHPE-L) and confirm that
the audio signal output level is 8kHz.
(3) Adjust Azimuth Adj. Screw so that the output level on the
AC Voltmeter or the waveform on the oscillo scope is at
maximum. (Fig. 6)
Note:
Upon completion of the adjustment of Azimuth Adj. Screw,
check the X Value by pushing the “PR +” or “PR -“buttons on
the unit alternately, to check the symmetry of the envelope.
Check the number of pushes to ensure preset position. The
number of pushes of the “PR +“ button on the unit to achieve
1/2 level of envelope should match the number of pushes of
the “PR -”button on the unit from center. If required, redo the
“X Value Alignment.”
4.4.2.5Checking and Alignment of Tape Path during reversing
Purpose:
To make sure that the tape path is well stabilized during reversing.
Symptom of Misalignment:
If the tape path is unstable during reversing, the tape will be
damaged.
Note:
Do not use an Alignment Tape for this proce dure. If the unit is
not correctly aligned, the tape may be damaged.
(1) Insert a blank cassette tape into the tray and set the unit to
REV. Then confirm if the tape has been curled up or bent
at the Take-up Guide Post[4] or REV Post[5]. (Refer to Fig.
11 and 12.)

5.4ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the individual
gears and levers that make up the tape loading/unloading mechanism. Since information about the state of the mechanism is
provided to the System Control Circuit only through the Mode
Switch, it is essential that the correct relationship between individual gears and levers be maintained.
All alignments are to be performed with the mechanism in
Eject mode, in the sequence given. Each procedure assumes
that all previous procedures have been completed.
IMPORTANT:
If any one of these alignments is not performed properly, even
if off by only one tooth, the unit will unload or stop and it may
result in damage to the mechanical or electrical parts.
5.4.1 Alignment points in Eject Position
5.4.1.1Alignment 1
Loading Arm (SP) and (TU) Assembly
Install Loading Arm (SP) and (TU) Assembly so that their triangle marks point to each other as shown in Fig. 2.
5.4.1.2Alignment 2
Mode Gear
Keeping the two triangles pointing at each other, install the
Loading Arm (SP) Assembly so that the last tooth of the gear
meets the most inside teeth of the Mode Gear. See Fig. 2.

WARNING
Notes:
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often
pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement parts that have these special safety
characteristics are identified in this manual and its supplements; electrical components having such features
are identified by the mark " " in the schematic diagram and the parts list. Before replacing any of these
components, read the parts list in this manual carefully. The use of substitute replacement parts that do not
have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards.
1. Do not use the part number shown on these drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since these drawings were prepared.
2. All resistance values are indicated in ohms (K=10
3
, M=106).
3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in uF (P=10
-6
uF).
5. All voltages are DC voltages unless otherwise specified.
6. Electrical parts such as capacitors, connectors, diodes, IC's, transistors, resistors, switches, and fuses are
identified by four digits. The first two digits are not shown for each component. In each block of the diagram,
there is a note such as shown below to indicate these abbreviated two digits.
LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC
DIAGRAMS ON THE FOLLOWING PAGES:
1. CAUTION:
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE FUSE.
2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, first check to see that all components in the power supply circuit are not
defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components
in the power supply circuit to fail.
3. Note:
1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since the drawings were prepared.
2. To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.
4. Voltage indications for PLAY and REC mode on the schematics are as shown below:

NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
Because a hot chassis ground is present in the power
supply circut, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly, when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
