Thread a TEAC YTT-8013 test tape. tn this case, either use of 7
inch reels or 10 inch are permitted provided both left and right
reels are the same size. ,
During fast forward or rewind mode, adjust R289 so that wave-
should be satisfied at any tape winding position.
Check that almost equal value of fast winding speed is obtained
between fast forward and rewind modes.

2-10 TENSION ARM HEIGHT ADJUSTMENT
1.
Thread any standard tape on the deck using a standard empty
reels such as TEAC RE-1002.
Set the deck in the forward play or fast-forward (fast rewind)
mode.
Stop left (right) guide roller's rotation by hand.
Adjust by turning the left (right) tension arm height adjusting
nut (refer to Fig. 2-11) so.that the tape moves in the center of
the guide roller.
Release the guide roller. Fine-adjust the adjust nut again so that
there is no evident tape curling on the left-most (right-most)
tape guide pin of the head assembly.
After adjusting the height of both left and right tension arms,
check that the tape running condition is good by switching be-
tween fast forward and rewind modes.
If the tape running position is different when the guide roller
stops and when it turns, the condition when the gulde roller is
rotating has priority.

2-11 REEL TABLE HEIGHT ADJUSTMENT
1. Adjust the tension arm height beforehand (See 2-10).
2. Check each reel table height using a TEAC RE-1002 empty reel
and letting the tape run in each tape operating mode.
3. If the tape rubs against the reel flanges, adjust the reel table
height by means of the two reel table mounting screws,

NOTE:
The adjustments referred to in this section are so closely related to
one another that it is necessary to re-check the other adjustments
after completion of one.
