2-17 WOW AND FLUTTER CHECKS
NOTES: 1. All the following apply to both forward and reverse
play modes.
2. The following measurements should be made at the
beginning and the end of the tape.
3. When ordering test tapes, allow for the longer delivery
time that is required for them.
Playback
1. Connect the test equipment to the deck as shown in Fig. 2-14.
2. Load and play a TEAC YTT-2003 test tape for HIGH speed (19
cm/s or 7-% ips), or a TEAC YTT-2002 test tape for LOW speed
(9.5 cm/s or 3-% ips).
3. Read the indication on the wow and flutter meter.
Specifications:
HIGH speed: 0.05% WRMS
0.10% RMS
LOW speed: 0.07% WRMS
0.12% RMS
Overall
4, Load a TEAC YTT-8013 test tape (blank). Apply and record a
3,000 Hz signal.
5. During simultaneous tape monitoring (playing) the recorded
signal, read the wow and flutter meter display.
Specifications:
HIGH speed: 0.12% RMS
LOW speed: 0.15% RMS

2-18 VOLTAGE CONVERSION
(FOR GENERAL EXPORT MODELS)
Always disconnect the power line cord before making these
adjustments.
Frequency Conversion
Since the X series uses DC motors, frequency conversion is not
necessary.
Voltage Conversion
1. First remove the two feet by removing the screws in each one.
2. Unscrew the left and right sides of the cabinet.
3. Locate the voltage selector to the right of the power trans-
former as seen from the rear of the deck.
4. Turn the slotted center post of the selector with a screw-driver
until the desired voltage numerals appear in the cut-out section
of the selector.
5. Replace the cabinet and feet.

2-19 LUBRICATION
Oiling is needed after every 1,000 hours of operation or once a year
if the deck is infrequently used. For this purpose, TEAC spindle oil
(from TEAC TZ-255 oil kit), Mobil D.T.E. Oil Light, etc are re-
commended. Lubrication is normally not necessary except at the
points shown.
1, Place the deck in the horizontal position.
2. Apply a few drops of oil to the respective spindles shown, ex-
cluding capstans, then spread the oil evenly on the spindle sur-
faces using a cotton cloth, etc.
3. For capstans, apply a few drops to the indicated position.
4. After oiling all the points, leave the deck for 1 to 2 hours until
the oil is thoroughly absorbed.
