4.3.2 Normal Forward Drive
Supply turntable. Fig. 4.17.
The supply turntable is free in normal forward drive
mode. The delrin knob on the clutch lever 990228 is
held in upper position by the operating lever 248186.
The delrin bushing 202230 and the friction disc 209658
are pressed down.
Adjustment:
Adjust screw A until the spacing between the friction
disc and the felt ring underneath the turntable is
between 0.5 and 1 mm (20-40 mil). Check clutch
lever positions in all operating modes, and seal
screw A.
Take-up turntable. Fig. 4.18.
In normal forward drive the take-up turntable has a
winding torque which is just sufficient to wind the
tape in record or playback mode. The operating arm
holds the delrin knob on the lever in an intermediate
position. The upper clutch lever 990229 will press
down the lower clutch lever 202740 thereby releasing
the pressure of the friction disc against the turntable.
The friction disc is pressed against the turntable felt
ring by the spring 218415.
Adjustments:
By means of screw B, bring the studs of bushing
202230 to a position half-way between upper and
lower clutch levers. The winding torque should
amount to 120-200 g cm (1.7-2.8 oz. in). Check the
position of the levers in all operating models and seal
screw B.
