1. MECHANICAL ADJUSTMENT

1-1  Wow and flutter (playback method)

In both FWD and REV play modes, these measurements
should be made at the beginning, middle, and the end of the
tape.

1. Connect a wow-and-flutter meter to the LINE OUT.

2. Load and play a TEAC MTT-111N test tape.

3. Check that the readings on the wow-and-flutter meter is

within 0.25% (JIS WTD).

1-2 Tape 

speed

1. Connect a frequency counter to the LINE OUT.

2. Load a TEAC MTT-111N test tape and play in FWD direc-

tion the beginning of the test tape.

3. Adjust each variable resistor to get the following values.

4. In play mode, check that the following values are obtained

at the beginning and end of the tape.

Speed drifting

Within 120Hz (HIGH speed)
Within 60Hz (LOW speed)

1-3 Reel 

torque

1. Load the cassette torque meter on the deck and read the

pointer indication on the dial scale for each tape transport
operation. The measured torque should be within the
following specified values.

Take-up: 

30 to 75g-cm

Supply: 

1.5 to 6g-cm

FF/REW: 

55 to 170g-cm
