6.2.2.5.2 AUDIO CONTROL HEAD TILT
ADJUSTMENT
TOP PREVIOUS NEXT
●
Purpose:
To confirm that the tape runs smoothly. In particular, confirm that the tape properly picks up
the Audio Signal at the upper part of the head and the Control Signal at the lower part of the
head.
●
Symptom of Misadjustment:
If the tilt of the Audio Control Head is poorly adjusted, the tape will eventually be damaged.
An intermittent Blue screen may be seen in Playback.
1. Play back a T120 cassette tape and check that the tape travels smoothly between the upper and
lower guides of the P4 post.
2. If necessary, adjust Black Screw (B) clockwise until the tape begins to curl at the lower edge of
the P4 post. Then adjust the screw counterclockwise until the curling is eliminated.
