2-12-2 HEAD TILT AND AZIMUTH ADJUSTMENT
1.
Visually adjust the tilt of playback and record heads so that the
head surface is parallel to the nearest tape guide or capstan shaft.
Make coarse azimuth adjustments for the record and playback
head, viewing each head from front (without tape).
2-12-3 TAPE GUIDE HEIGHT ADJUSTMENT
1.
Playing a TEAC YTT-8013 test tape (thickness = 35m), adjust
the height of the left tension arm so that the lower edge of the
tape is just touching the lower edge of the tape guide (1). See
Fig. 2-19. Also refer to “2-10 TENSION ARM HEIGHT ADJUST-
* MENT”.
Adjust the height of the tape guide (2) so that the upper edge of
the tape is in contact with the upper edge of the tape guide.
Confirm that the adjustments do not cause the tape to curl.
Adjust height of tape guides (3) and (4) in the same way as steps
1~3. For tape guide (4), adjust right tension arm height.
Check to see there is no tape curling at all the tape guides.
Apply locking paint to the height adjust nut of tape guides (2)
and (3).

2-12-4 FINE ADJUSTMENT OF PINCH ROLLER
PARALLELISM
With HIGH tape speed, each pinch roller should satisfy the follow-
ing requirements.
1. Remove pinch roller cap.
2. Manually move pinch roller upwards (along pinch roller spindle)
by 1 ~ 2mm from the stop portion of the spindle, then play a
test tape.
3. During play mode, observe whether the pinch roller position
changes in the spindle direction. :
4. lf a change is found, re-adjust accurately tilt of pinch roller
spindle by method illustrated in Fig. 2-18.
2-12-5 HEAD HEIGHT ADJUSTMENT
1. On X-1000M model, fine-adjust the height of the 2T record and
2T playback heads so that their head cores are equally distant
from the upper and lower edges of the tape.
2. Fine-adjust the height of the 4T record and 4T playback head(s)
so that the head’s brass-colored spacer shows just above the mav-
ing tape (about the thickness of a thin pencil line).

TEAC Tape Speed and Flutter test tapes:
YTT-2004: For 38cm/s (15 ips) speed
YTT-2003: For 19cm/s (7-% ips) speed
YTT-2002: For 9.5cm/s (3-% ips) speed
1. Connect a frequency counter to either OUTPUT terminal.
2. Load a TEAC YTT-2004 (X-1000: YTT-2003) test tape. Set the
SPEED switch—HIGH, and PITCH CONT knob—OFF.
3. Play the tape. Adjust HIGH SPEED control (see Fig. 2-22) fora
reading of 3,000Hz +5Hz.
4. Check the following at the beginning and the end of the tape.
Specifications:
Tape speed deviation .............. 3,000Hz +30Hz
Tape speed drift ... 2... eee ee .. I5Hz
5. Change the test tape to a TEAC YTT-2003 (X-1000: YTT-2002),
and SPEED switch setting to LOW.
6. Repeat steps 3 through 4. Adjust LOW SPEED control if neces-
sary.
7. Pull the PITCH CONT knob out. Set SPEED switch HIGH. Play
a YTT-2004 (X-1000: YTT-2003) tape.
