Method : Play back the 8kHz signal of the test tape and

adjust so that the output becomes maximum.

7. Tape speed adjustment Settings : Test tape : TTA-100 (TAPE CENTER)

Test point : PHONES JACK (J101) Adjustment location : SFR101

Method : Play back the test tape and adjust for 3015 ± 10 Hz.

8. GOVERNOR Adjustment 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 procedure below.

1) Solder only medium resistor pattern (B) of the MOTOR

AND GOVERNOR MATCHING ADJ. resistor group.

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

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

4)Remove your hand and listen to the begining 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.

Pattern

High resistance(C)

Medium resistance(B)

Low resistance(A)

7) Finally re-check the tape speed.

Caution: Cool the patterns down to normal temperature after soldering. If the pattern remains heated, the governor circuit does not operate normally.
