ADJUSTMENT
<TAPE PLAYER SECTION>
1. Tape Speed Adjustment
Settings : • Test tape : TTA-100 (TAPE CENTER)
• Test point : PHONES (J101)
• Adjustment location : SFR101
• Super Bass : OFF
• Volume : MAX
Method : Play back the test tape and adjust SFR101 for 3000Hz
± 10Hz (FWD).
Then confirm WOW is less than 0.50%.
2. Azimuth Adjustment
Settings : • Test tape : TTA-330
• Volume : MAX
• Adjustment location : Head azimuth adjustment
screw
Method : Play back (FWD) the test tape and adjust screw so
that the 8kHz signal output is maximum.
< TUNER SECTION >
1. AM IF Adjustment
IFT201 .................................... 450kHz <TX426 / 429>
IFT601 .................................... 450kHz <TX427>
2. AM Tracking Adjustment
L201 ........................................ 630kHz <TX426 / 429>
TC201 ..................................... 1440kHz <TX426 / 429>
L601 ........................................ 630kHz <TX427>
TC601 ..................................... 1440kHz <TX427>
3. FM IF Adjustment
TC501 ..................................... 10.7MHz <TX427>
4. FM Tracking Adjustment
L202 ........................................ 76MHz <TX426 / 429>
L502 ........................................ 71.75MHz (TV 4ch) <TX427>
5. FM VT Adjustment
Settings : • Test point : TP1 (VT)
• Adjustment location : L203 <TX426 / 429>
L504 <TX427>
* Short IC501 Pin 6 (PA0) and Pin 7 (PB3) together. <TX426 / 429>
* Connect cathode of diode to Pin 6 (PA0) and anode to Pin 7 (PB3)
of IC801. <TX427>
Method : Set to FM 76MHz <TX426 / 429>, FM 59MHz <TX427>
and adjust L203 <TX426 / 429>, L504 <TX427> so that
the test point becomes 1.1V ± 0.1V <TX426 / 429>, 1.4V
± 0.1V <TX427>. Then set to FM 108.1MHz and check
that the test point is less than 7V <TX426 / 429>, less
than 11V <TX427>.
6. TV Tracking Adjustment <TX427>
L501 ........................................ 162.4MHz (WEATHER 2ch)
7. TV VT Adjustment <TX427>
Settings : • Test point : TP1 (VT)
• Adjustment location : L503
* Connect cathode of diode to Pin 6 (PA0) and anode to Pin 7
(PB3) of IC801.
Method : Set to 162.4MHz (TV 1ch) and adjust L503 so that the test
point becomes 2.0V ± 0.1V. Then set to 215.75MHz
(TV 5ch) and check that the test point is less than 10V.
