IMPORTANT SAFETY PRECAUTIONS

Prior to shipment from the factory, our products are strictly inspected for 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.

Safety Precautions for TV Circuit

1. Before returning an instrument to the custom­er, always make a safety check of the entire instru-

ment, including, but not limited to, the following
items:

a. Be sure that no built-in protective devices are de-

fective and have been defeated during servicing.
(1) Protective shields are provided on this chassis
to protect both the technician and the customer.
Correctly replace all missing protective shields, in­cluding any removed for servicing convenience.
(2) When reinstalling the chassis and/or other as­sembly in the cabinet, be sure to put back in place
all protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not oper-

ate this instrument or permit it to be operated
without all protective devices correctly in­stalled and functioning. Servicers who defeat
safety features or fail to perform safety checks
may be liable for any resulting damage.

b. Be sure that there are no cabinet openings through

which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to, (1) spac­ing between the picture tube and the cabinet
mask, (2) excessively wide cabinet ventilation
slots, and (3) an improperly fitted and/or incorrectly
secured cabinet back cover.

c. Antenna Cold Check - With the instrument AC

plug removed from any AC source, connect an
electrical jumper across the two AC plug prongs.
Place the instrument AC switch in the on position.
Connect one lead of an ohmmeter to the AC plug
prongs tied together and touch the other ohmme­ter lead in turn to each tuner antenna input ex­posed terminal screw and, if applicable, to the
coaxial connector. If the measured resistance is
less than 1.0 megohm or greater than 5.2 mego­hm, an abnormality exists that must be corrected
before the instrument is returned to the customer.
Repeat this test with the instrument AC switch in
the off position.

d. Leakage Current Hot Check - With the instru-

ment completely reassembled, plug the AC line
cord directly into a 120V AC outlet. (Do not use an
isolation transformer during this test.) Use a leak-

age current tester or a metering system that com­plies with American National Standards Institute
(ANSI) C101.1 Leakage Current for Appliances
and Underwriters Laboratories (UL) 1410, (50.7).
With the instrument AC switch first in the on posi­tion and then in the off position, measure from a
known earth ground (metal water pipe, conduit,
etc.) to all exposed metal parts of the instrument
(antennas, handle brackets, metal cabinet, screw
heads, metallic overlays, control shafts, etc.), es­pecially any exposed metal parts that offer an elec­trical return path to the chassis. Any current
measured must not exceed 0.5 milli-ampere. Re­verse the instrument power cord plug in the outlet
and repeat the test.

THE CUSTOMER OR BEFORE CONNECTING
THE ANTENNA OR ACCESSORIES.

e. X-Radiation and High Voltage Limits - Because

the picture tube is the primary potential source of
X-radiation in solid-state TV receivers, it is special­ly constructed to prohibit X-radiation emissions.
For continued X-radiation protection, the replace­ment picture tube must be the same type as the
original. Also, because the picture tube shields
and mounting hardware perform an X-radiation
protection function, they must be correctly in place.
High voltage must be measured each time servic-

1-1-1 T6550SFTY

ing is performed that involves B+, horizontal de­flection or high voltage. Correct operation of the
X-radiation protection circuits also must be recon­firmed each time they are serviced. (X-radiation
protection circuits also may be called "horizontal
disable" or "hold down.") Read and apply the high
voltage limits and, if the chassis is so equipped,
the X-radiation protection circuit specifications giv­en on instrument labels and in the Product Safety
& X-Radiation Warning note on the service data
chassis schematic. High voltage is maintained
within specified limits by close tolerance safety-re­lated components/adjustments in the high-voltage
circuit. If high voltage exceeds specified limits,
check each component specified on the chassis
schematic and take corrective action.

2. Read and comply with all caution and safety-relat­ed notes on or inside the receiver cabinet, on the
receiver chassis, or on the picture tube.

3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of this TV re­ceiver. Design alterations and additions, including,
but not limited to circuit modifications and the ad­dition of items such as auxiliary audio and/or video
output connections, might alter the safety charac­teristics of this receiver and create a hazard to the
user. Any design alterations or additions will void
the manufacturer's warranty and may make you,
the servicer, responsible for personal injury or
property damage resulting therefrom.

4. Picture Tube Implosion Protection Warning -

The picture tube in this receiver employs integral
implosion protection. For continued implosion pro­tection, replace the picture tube only with one of
the same type number. Do not remove, install, or
otherwise handle the picture tube in any manner
without first putting on shatterproof goggles
equipped with side shields. People not so
equipped must be kept safely away while picture
tubes are handled. Keep the picture tube away
from your body. Do not handle the picture tube by
its neck. Some "in-line" picture tubes are equipped
with a permanently attached deflection yoke; be­cause of potential hazard, do not try to remove
such "permanently attached" yokes from the pic­ture tube.

5. Hot Chassis Warning -

a. Some TV receiver chassis are electrically connect-

ed directly to one conductor of the AC power cord
and maybe safety-serviced without an isolation
transformer only if the AC power plug is inserted
so that the chassis is connected to the ground side
of the AC power source. To confirm that the AC
power plug is inserted correctly, with an AC volt­meter, measure between the chassis and a known

earth ground. If a voltage reading in excess of 1.0V
is obtained, remove and reinsert the AC power
plug in the opposite polarity and again measure
the voltage potential between the chassis and a
known earth ground.

b. Some TV receiver chassis normally have 85V

AC(RMS) between chassis and earth ground re­gardless of the AC plug polarity. This chassis can
be safety-serviced only with an isolation transform­er inserted in the power line between the receiver
and the AC power source, for both personnel and
test equipment protection.

c. Some TV receiver chassis have a secondary

ground system in addition to the main chassis
ground. This secondary ground system is not iso­lated from the AC power line. The two ground sys­tems are electrically separated by insulation
material that must not be defeated or altered.

6. Observe original lead dress. Take extra care to as­sure correct lead dress in the following areas: a.
near sharp edges, b. near thermally hot parts-be
sure that leads and components do not touch ther­mally hot parts, c. the AC supply, d. high voltage,
and e. antenna wiring. Always inspect in all areas
for pinched, out of place, or frayed wiring. Check
AC power cord for damage.

7. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged
should be replaced with components, parts, or wir­ing that meet original specifications. Additionally,
determine the cause of overheating and/or dam­age and, if necessary, take corrective action to re­move any potential safety hazard.

8. 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 strictly 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 T6550SFTY

Precautions during Servicing

A. Parts identified by the ( ! ) symbol are critical for

safety.

Replace only with part number specified.

B. In addition to safety, other parts and assemblies

are specified 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.

C. Use specified internal wiring. Note especially:

1) Wires covered with PVC tubing

2) Double insulated wires

3) High voltage leads

D. Use specified insulating materials for hazardous

live parts. Note especially:

1) Insulation Tape

2) PVC tubing

3) Spacers

4) Insulators for transistors.

E. When replacing AC primary side components

(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before solder­ing.

F. Observe that the wires do not contact heat produc-

ing parts (heatsinks, oxide metal film resistors, fus­ible resistors, etc.)

G. Check that replaced wires do not contact sharp

edged or pointed parts.

H. When a power cord has been replaced, check that

5~6 kg of force in any direction will not loosen it.

I. Also check areas surrounding repaired locations.

J. Use care that foreign objects (screws, solder drop-

lets, etc.) do not remain inside the set.

K. Crimp type wire connector

When replacing the power transformer in sets
where the connections between the power cord
and power transformer primary lead wires are per­formed using crimp type connectors, in order to
prevent shock hazards, perform carefully and pre­cisely the following steps.

Replacement procedure

1) Remove the old connector by cutting the wires at a
point close to the connector.

Important: Do not re-use a connector (discard it).

2) 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.

3) Align the lengths of the wires to be connected. In­sert the wires fully into the connector.

4) Use the crimping tool to crimp the metal sleeve at
the center position. Be sure to crimp fully to the
complete closure of the tool.

L. When connecting or disconnecting the VCR con-

nectors, first, disconnect the AC plug from AC sup­ply socket.

1-1-3 T6550SFTY

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 original positions.
Afterwards, perform the following tests and confirm the
specified values in order to verify compliance with
safety standards.

1. Clearance 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)

How to Remove / Install Flat Pack IC

Caution:

1. The Flat Pack-IC shape may differ by models. Use
an appropriate hot-air flat pack-IC desoldering ma­chine, whose shape matches that of the Flat Pack­IC.

2. Do not apply the hot air to the chip parts around the

Flat Pack-IC for over 6 seconds as damage may
occur to the chip parts. Put Masking Tape around
the Flat Pack-IC to protect other parts from dam­age. (Fig. S-1-2)

3. The Flat Pack-IC on the CBA is affixed with glue, so

be careful not to break or damage the foil of each
pin or solder lands under the IC when removing it.

1. Removal

With Hot - Air Flat Pack - IC Desoldering Machine:

a. Prepare the Hot - Air Flat Pack - IC Desoldering

Machine, then apply hot air to Flat Pack - IC (about
5~6 seconds). (Fig. S-1-1)

b. Remove the Flat Pack- IC with tweezers while

applying the hot air.

With Soldering Iron:

a. Using desoldering braid, remove the solder from all

pins of the Flat Pack - IC. When you use solder flux
which is applied to all pins of the Flat Pack - IC, you
can remove it easily. (Fig. S-1-3)

b. Lift each lead of the Flat Pack - IC upward one by

one, using a sharp pin or wire to which solder will
not adhere (iron wire). When heating the pins, use
a fine tip soldering iron or a hot air Desoldering
Machine. (Fig. S-1-4)

With Iron Wire:

a. Using desoldering braid, remove the solder from all

pins of the Flat Pack - IC. When you use solder flux
which is applied to all pins of the Flat Pack - IC, you
can remove it easily. (Fig. S-1-3)

1-2-2 SFTY_Z13P

b. Affix the wire to a workbench or solid mounting

point, as shown in Fig. S-1-5.

c. Pull up on the wire as the solder melts so as to lift

the IC leads from the CBA contact pads, while
heating the pins using a fine tip soldering iron or
hot air blower.

Note:

When using a soldering iron, care must be taken
to ensure that the Flat Pack - IC is not being held
by glue, or when it is removed from the CBA, it
may be damaged if force is used.

2. Installation

a. Using desoldering braid, remove the solder from

the foil of each pin of the Flat Pack - IC on the CBA,
so you can install a replacement Flat Pack - IC
more easily.

b. The "I" mark on the Flat Pack - IC indicates pin 1

(See Fig. S-1-6). Make sure this mark matches the
1 on the CBA when positioning for installation.
Then pre - solder the four corners of the Flat Pack­IC (See Fig. S-1-7).

c. Solder all pins of the Flat Pack - IC. Make sure that

none of the pins have solder bridges.

1) POWER SAFETY 1

If P-SAFETY 1 port becomes continuously 2.5V or
less for 120 msec. (4 times 40 msec. interval) when
MONITOR is ON, the unit shall be assumed to be
the Power Malfunction 1 and immediately turn OFF
the POWER/MONITOR and switch over the
Mechanical Malfunction mode with POWER OFF.

(To return from this mode shall become possible
only by POWER Key as in the case of the Mechan­ical Malfunction).

* However the POWER SAFETY 1 function shall be
disabled during 500 msec. right after the MONI­TOR tur ns ON.

2) POWER SAFETY 2

If P-SAFETY 2 port becomes continuously 2.5V or
less for 120 msec. (4 times 40 msec. interval) when
P-ON-H port is ON, the unit shall be assumed to be
the Power Malfunction 2 and immediately turn OFF
the POWER/MONITOR and switch over the
Mechanical Malfunction mode with POWER OFF.

(To return from this mode shall become possible
only by POWER Key as in the case of the Mechan­ical Malfunction).

* However the POWER SAFETY 2 function shall be
disabled during 500 msec. right after the P-ON-H
port turns ON.

X-RAY protect

If X-RAY port becomes continuously 2.5V or more for
120 msec. (4 times 40 msec. interval), the unit shall
immediately turn OFF the POWER/MONITOR and
switch over to the Mechanical Malfunction mode with
POWER OFF.

(To return from this mode shall become possible only

Mechanical Malfunction determination

1) REEL Malfunction detection

Countermeasure for REEL and CAPSTAN motor
rotation malfunction (Except CASSETTE LOAD­ING function)

After the Malfunction detection with REEL/CAP­STAN sensor, the unit shall switch over to STOP
(B) and be REEL Mechanical Malfunction.

a) If the T-REEL pulse is not impressed after a lapse

of 7 sec. at SP, 14 sec. at LP, or more in the REEL
Rotation Mode like PLAY/REC, FS/RS Mode, and
the T-REEL or S-REEL pulse is not impress after a
lapse of 4 sec. or more in REEL Rotation Mode of
FF/REW, it shall be assumed to stop the rotation
and switch over to STOP (B) position, then
POWER be turned OFF and the unit be REEL
Mechanical Malfunction. (T-REEL and S-REEL for
the models on S-REEL and only T-REEL for other
models)

b) If the C-FG pulse is not impressed for a lapse of 1

sec. or more during the CAPSTAN MOTOR rota­tion, it shall be MOTOR Rotation Malfunction
(REEL Malfunction).

2) DRUM Malfunction detection

Detect the DRUM rotation at the D-FG input termi­nal.

If the variation of D-FG input level is not detected
for a lapse of 1 sec. or more when D-CONT is "H",
it shall be assumed to be Rotation Malfunction and
be DRUM Malfunction.

When detect Drum Malfunction, POWER shall be
turned OFF after the unit switches over to STOP
(B) Mode.

3) Countermeasure for TAPE LOADING Malfunction

Detect the Malfunction with the LOADING Switch.

a) TAPE LOADING Malfunction

If LD-SW does not go to the established position
after a lapse of 7 sec. or more from TAPE LOAD­ING or TAPE UNLOADING start, the LOADING
function shall immediately be stopped and POWER
be turned OFF, and inform the Timer about the
LOADING Mechanical Malfunction.

b) LD-SW Position Malfunction at each mode

When the unit operates at each mode, even if the
LD-SW position changes from the established one
in its mode, it keeps the function according to its
mode.

4) Countermeasure for CASSETTE LOADING Mal­function

a) CASSETTE IN operating Malfunction

If LD-SW does not go to SB position after a lapse
of 5 sec. or more from the CASSETTE insertion
start, the unit starts the CASSETTE OUT opera­tion.

After switch over to CASSETTE OUT operation and
then a laps of 5 sec. or more from the CASSETTE
OUT operation start, if LD-SW does not go to the
EJ position or if START Sensor and END Sensor
does not turn "ON" at the EJ position, the unit
starts again to insert CASSETTE.

(However in S-INH state, the START/END Sensor
shall be disabled).

b) CASSETTE OUT operating Malfunction

After a lapse of 5 sec. or more from CASSETTE
OUT operation start, if LD-SW does not go to the
EJ position or if START Sensor and END Sensor
does not turn "ON" at the EJ position, the unit
starts to insert CASSETTE.

(However in S-INH state, the START/END Sensor
shall be disabled).

When the unit switches over to CASSETTE inser­tion at CASSETTE IN or CASSETTE OUT Mal­function, if LD-SW does not go to the SB position
after a lapse of 5 sec. or more from CASSETTE
insertion start, the function shall immediately be
stopped and POWER be turned OFF, and the unit
be CASSETTE LOADING Malfunction.

c) When POWER is turned ON, if the CL position or

GC position cannot be detected after 5 sec. LD­REV operation and 5 sec. LD-FWD operation, the
function shall immediately be stopped and POWER
be turned OFF, and the unit be CASSETTE LOAD­ING Malfunction.

d) When POWER is turned ON without CASSETTE

(EJ position) and LD-SW is monitored all the time,
if the CL or GC position is detected continuously for
1 sec. or more, the POWER shall be turned OFF
and the unit be CASSETTE LOADING Malfunction.

Countermeasure for Mechanical
Malfunction

If the unit detects Mechanical Malfunction, turn the
POWER OFF. If the unit is Mechanical Malfunction,
Key input except POWER key shall be disabled and
CASSETTE insertion disabled. When POWER Key is
entered, the POWER is turned ON and the unit
switches over the EJECT Mode. (Return with POWER
ON)

WARNING

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.

Notes:

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. 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.

3. Prefix symbol "CN" means "connector" (can dis­connect and reconnect).
Prefix symbol "CL" means "wire-solder holes of the
PCB" (wire is soldered directly).

4. How to read converged lines.

CAUTION !

Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.
If Main Fuse (F601) is blown, 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.

CAUTION

FOR CONTINUED PROTECTION AGAINST FIRE HAZARD,

REPLACE ONLY WITH THE SAME TYPE FUSE.

NOTE :
The voltage for parts in hot circuit is measured
using hot GND as a common terminal.

(H Adjustment)

BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER

SUPPLY CIRCUIT, 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.

MECHANICAL ALIGNMENT PROCEDURES

Explanation of alignment for the tape to correctly run
starts on the next page. Refer to the information below
on this page if a tape gets stuck, for example, in the
mechanism due to some electrical trouble of the unit.

Service Information

A. Method for Manual Tape Loading/Unloading

To load a cassette tape manually:

1. Disconnect the AC plug.

2. Remove the Top Case and Front Assembly.

3. Insert a cassette tape. Though the tape will not be
automatically loaded, make sure that the cassette
tape is all the way in at the inlet of the Cassette
Holder. To confirm this, lightly push the cassette
tape further in and see if the tape comes back out,
by a spring motion, just as much as you have
pushed in.

4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 for a minute or two to complete
this task.

To unload a cassette tape manually:

1. Disconnect the AC plug.

2. Remove the Top Case and Front Assembly.

3. Make sure that the Moving guide preparations are
in the Eject Position.

4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 until the Moving guide prepara­tions come to the Eject Position. Stop turning when
the preparations begin clicking or can not be
moved further. However, the tape will be left wound
around the cylinder.

5. Turn the LDG Belt in the appropriate direction con­tinuously, and the cassette tape will be ejected.
Allow a minute or two to complete this task.

B. Method to place the Cassette Holder in the tape-

loaded position without a cassette tape

1. Disconnect the AC Plug.

2. Remove the Top Case and Front Assembly.

3. Turn the LDG Belt in the appropriate direction
shown in Fig. M1. Release the locking tabs shown
in Fig. M1 and continue turning the LDG Belt until
the Cassette Holder comes to the tape-loaded
position. Allow a minute or two to complete this
task.

1-A. Preliminary/Final Checking and

Alignment of Tape Path

Purpose:

To make sure that the tape path is well stabilized.

Symptom of Misalignment:

If the tape path is unstable, the tape will be damaged.

Note: Do not use an Alignment Tape for this proce­dure. If the unit is not correctly aligned, the tape may
be damaged.

1. Playback a blank cassette tape and check to see
that the tape runs without creasing at Guide Rollers
[2] and [3], and at points A and B on the lead sur­face. (Refer to Fig. M3 and M4.)

2. If creasing is apparent, align the height of the guide
rollers by turning the top of Guide Rollers [2] and
[3] with a Guide Roller Adj. Screwdriver. (Refer to
Fig. M3 and M5.)

TP001 (CTL) on the Main CBA. Use TP002 (RF­SW) as a trigger.

2. Playback the Gray Scale of the Alignment Tape
(9965 000 14516) and confirm that the PB FM sig­nal is present.

3. Set the Tracking Control Circuit to the preset posi­tion by pressing CH UP button on the remote con­trol unit then “PLAY” button on the unit. (Refer to
note on bottom of page 2-3-4.)

4. Use the Flat Screwdriver so that the PB FM signal
at TP008 (C-PB) is maximum. (Fig. M6)

3. Check to see that the tape runs without creasing at
Take-up Guide Post [4] or without snaking between
Guide Roller [3] and ACE Head. (Fig. M3 and M5)

5. To shift the CTL waveform, press CH UP or CH
DOWN button on the remote control unit. Then
make sure that the maximum output position of PB
FM envelope signal become within
set position.

1-C. Checking/Adjustment of Envelope

Waveform

Purpose:

To achieve a satisfactory picture, adjust 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 TP008 (C-PB) on the
Main CBA. Use TP002 (RF-SW) as a trigger.

2. Playback the Gray Scale on the Alignment Tape
(9965 000 14516). Set the Tracking Control Circuit
to the preset position by pressing CH UP button
and then “PLAY” button on the unit. Adjust the
height of Guide Rollers [2] and [3] (Fig. M3, Page
2-3-3) 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. M7, adjust the
height of Guide Roller [2] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.

4. If the envelope is as shown in Fig. M8, adjust the
height of Guide Roller [3] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.

Dropping envelope level at the end of track.

Note: Upon completion of the adjustment of Guide
Rollers [2] and [3] (Refer to Fig. M3), check the X
Value by pushing the CH UP or DOWN buttons alter­nately, to check the symmetry of the envelope. Check
the number of pushes to ensure preset position. The
number of pushes CH UP button to achieve 1/2 level of
envelope should match the number of pushes CH
DOWN button from center. If required, redo the “X
Value Alignment.”

1-D. Azimuth Alignment of Audio/Con-

trol/ 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 (9965 000 14516) and
confirm that the audio signal output level is 6kHz.

3. Adjust Azimuth Adj. Screw so that the output level
on the AC Voltmeter or the waveform on the oscillo­scope is at maximum. (Fig. M6)
