7. GOVERNER 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 procedures below. 1) Solder resistor pattern (A) of the MOTOR AND GOVERNOR MATCHING ADJ. resistor group. 2) Set the tape speed (using speed adjustment SFR101). 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 Pattern (Procedure 1 above) Step (1) Step (2) (NOTE :

Tape Speed Adjustment Settings : · Test tape : TTA100 (Tape center) · Test point : PHONES (J101) · Adjustment location : SFR101 · MSP : CLASSIC · TAPE SELECTOR : NORM · VOLUME : MAX Method : Play back (FWD) the test tape and adjust SFR101 so that the frequency becomes 3010Hz±10Hz. Then confirm WOW is less than 0.50%.

7) Finally re-check the tape speed.
Caution : Cool the patterns down to normal temperature after soldering. If the pattern remains heated, the gorvernor circuit does not operate normally.
