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 taperun. 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.
