2-1 MECHANICAL ADJUSTMENT
2-1-1 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
0.19% (JIS WTD).
2-1-2 Tape speed
1. Connect a frequency counter to the LINE OUT.
2. Load a TEAC MTT-111N test tape and play in FWD direction
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)
2-1-3 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.
