Adjustment method
Measuring instructions required for
adjustment
1. AM signal generator
2. FM signal generator
3. Inter mediate frequency sweep generator
4. FM stereo signal generator
5. Low-frequency oscillator
(oscillation frequency 50Hz-20kHz, 0dB output
with 600 ohm impedance)
6. Attenuator (600 ohm impedance)
7. Electronic voltmeter
8. Distortion meter
9. Torque gauge (cassette for CTG-N)
10. Wow & flutter meter
11. Frequency counter meter
12. Test tape
VT712 : For tape speed and wow flutter
VT724 : For reference level
VT702 : For playback frequency
VT702 : For head azimuth adjustment
13. Blank tape
TAPE : AC-225
