1. Tape Speed Adjustment Settings : • Test tape : TTA – 100

(Tape center)

• Test point : Phones Jack (J1)

• Adjustment location : SFR51

• Tape selector : NORM

• Volume : Non – clip (MAX – 10 dB down)

Method : Play back the test tape and adjust SFR51 so that the

frequency becomes 3000 Hz ± 10 Hz. Then confirm WOW is less than 0.52%.

2. Dolby Level Adjustment Settings : • Test tape : TTA – 200

• Test point : TP1 (L – CH) TP2 (R – CH)

• Adjustment location : SFR1 (LCH) SFR2 (RCH)

• Dolby NR : OFF

• Tape selector : NORM

Method : Play back (FWD) the test tape and adjust SFRs so that

the test point becomes 100 mV ± 1 dB.

3. Head Azimuth Adjustment Setting : • Test tape : TTA – 330 / TTA – 420

• Volume : MAX

• Tape selector : NORM

• Adjustment location : Head azimuth adjustment screw

Method : Play back (FWD) the test tape and adjust screw so that

the 8 kHz signal output is maximum.

4. GOVERNER Check Perform the STOP —> PLAY and REVERSE operations (or PAUSE ON —> OFF) after the motor is replaced. When the tape starts running smooth, this adjustment is not necessary. If wow is conspicuous at the beginning of the tape-run, perform this adjustment

following the procedures below.

1) Solder resistor pattern (A) of the MOTOR AND GOVERNOR MATCHING ADJ. resistor group.

2) Set the tape speed (using speed adjustment SFR51).

3) Restrict the motor rotation by hand (or turn PAUSE ON).

4) Remove your hand and listen to the beginning of the tape-run.

5) When the rise of tape running is smooth, no more adjustment is necessary. If wow continues for 1 to 2 seconds at the rise time, change the combined resistance according to procedure 6 and check that the tape starts running smooth.

6) Solder the resistor pattern according to the table below
