Method : Set to FM 108.0 MHz and adjust the L907 so that the
test point is 7.00 V ± 0.05 V.
8. FM VT Check
Settings : • Test point :TP1 (VT)
Method : Set to FM 87.5 MHz check that the test point is more
than 0.5 V.
9. FM Tracking Adjustment
Settings : • Test point :TP8 (Rch), TP9 (Lch)
• Adjustment location: L904
Method : Set to FM 108 MHz and adjust L904 so that the test
point becomes maximum and distortion to minmum.
10. FM Tracking Check
Settings : • Test point :TP8 (Rch), TP9 (Lch)
Method : Set to FM 98.0 MHz and check that the test point
is less than 13 dBµV.
11. DC Balance / Mono Distortion Adjustment
Settings : • Test point :TP3, TP4 (DC Balance)
TP8 (Rch), TP9 (Lch)
(Mono Distortion)
• Adjustment location : L801
• Input level :60 dBµV
Method : Set to FM 98.0 MHz and adjust L801 so that the
voltage between TP3 and TP4 becomes 0 V ± 500 mV
with minimum distortion.
12. Output Level Check
<MW>
Settings : • Test point :TP8 (Rch), TP9 (Lch)
• Input level : 74 dBµV
Method : Set to MW 999 kHz and check that the test point is
55 mV ± 3 dB.
<FM>
Settings : • Test point :TP8 (Rch), TP9 (Lch)
• Input level : 60 dBµV
Method : Set to FM 98.0 MHz and check that the test point is
270 mV ± 3 dB.
13. FM Separation Check
Settings : • Test point :TP8 (Rch), TP9 (Lch)
• Input level :60 dBµV
Method : Set to FM 98.0 MHz and check that the separation
at the test point is more than 25 dB.
< DECK SECTION >
1. Tape Speed Check
Settings : • Test tape :TTA–100
• Test point :SP OUT
Method : Play back the test tape FWD / REV and
check the difference speed is ± 45 Hz.
2. Head Azimuth Adjustment
Settings : • Test tape :TTA–330
• Test point :SP OUT
• Adjustment location : Head azimuth
adjustment screw
Method : Play back FWD the 8 kHz signal of the test tape and
adjust screw so that the output becomes maximum.
Next, perform on REV PLAY mode.
3. PB Frequency Response Check
Settings : • Test tape :TTA–320
• Test point :SP OUT
Method : Play back the 315 Hz and 10 kHz signals of the test
tape and check that the 10 kHz signal with respect to
that of the 315 Hz signal is -3 dB ± 3 dB.
4. REC/PB Frequency Response Check
Settings : • Test tape :TTA–602
• Test point :SP OUT
• Input signal :8 kHz /1 kHz (-20 VU / 0 dB)
Method : Input a -20 VU signal to the VIDEO/AUX terminal.
Record the 1 kHz and 8 kHz signals on the test tape
and play back them. Check that the difference between
the record level and the play back level at 1 kHz and
8 kHz signal is -2 dB ± 3 dB.
