● As shown in Fig. 1,
if the amplitude of only either CH1 or CH2 is small, one of the 2 screws (#119)
may be loosened, so check for it. If this is not the case, the GMR sensor may malfunction so
replace it and make a readjustment.
●
As shown in Fig. 2, if the amplitude partially drops during the rotation, the magnetic data of the
tape of the focus turning-tube unit may be damaged. So replace the focus turning-tube unit and
make a readjustment.
