Teac X-1000 - 2-14 Wow and Flutter Checks

8. Check if the speed variation of at least 3,000Hz +180Hz is ob-
tained when the PITCH CONT knob is rotated fully in both
directions.
9. Change the test tape to YTT-2003 (X-1000: YTT-2002), SPEED
switch setting to LOW. Repeat step 8.

2-14 WOW AND FLUTTER CHECKS
. TEAC Tape Speed and Flutter test tapes:
Refer to the beginning of paragraph 2-13,
NOTE: The following measurements should be made at the begin-
ning and the end of the tape.
Playback
1. Connect the test equipment to the deck as shown in Fig. 2-21.
2. Load and play a TEAC YTT- 2004 (X-1000: YTT-2Z003) test tape
for HIGH speed.
3. Read the indication on the wow and flutter meter.
4. Repeat steps 2 through 3 using a TEAC YTT-2003 (X-1000:
TEAC YTT-2002) tape for LOW speed.
5. Wow and flutter specifications are as shown below.
X-1000M: HIGH (38cm/s): 0.04% WRMS 0.08% RMS
LOW (19cm/s): 0.05% WRMS 0.10% RMS
HIGH (19cm/s): 0.05% WRMS 0.10% RMS
LOW (9.5cm/s): 0.07% WRMS 0.12% RMS

Overall
6. Load a TEAC YTT-8013 test tape (blank). Apply and record a
3,000Hz signal.
7, During simultaneous tape monitoring (playing) the recorded
signal, read the wow and flutter meter display.

2-15 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 T2Z-255 oil kit), Mobil D.T.E. Oil Light, etc. are recom-
mended. 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, exclud-
ing capstans, then spread the oil evenly on the spindle surfaces
using a cotton cloth, etc.
. 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,

2-16 VOLTAGE CONVERSION
(FOR GENERAL EXPORT MODELS)
Always disconnect the power line cord before making these adjust-
ments.
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 above the power transformer as seen
from the rear of the deck.
4. Remove the plug by pulling it out, then re-insert it so that the
arrow on the piug is parallel with the white line indicating the
proper voltage.
5. Replace the cabinet and feet.
