Dual 704 - Starting and Shut Off Procedures; Adjustment Points

Starting
and
shut
off
Fig. 13
Turning the
tonearm (48) rotates
the segment
(205) thus
actuating the power
switch (106)
via pawl (135)
and shift arm
(146) and
start—
ing motor (18)
and platter
(4) rotating.
The
shut—off cycle
after placing a
record is
initated by the
dog (M) of the
platter (4)
and shut—off lever (163).
The
shut—off lever
(163) is guided
onto the
dog by
the movement of
the tonearm
when play—
ing the record
with the aid
of the shut—off
bar
(164)
proportionate to the
groove lead
(Fig. 13 a).
The
eccentrically—mounted
dog
forces
the shut—off
lever (163)
back with
each
revolution as long as
the advance
of
the tonearm
only amounts
to the width
of one
groove.
Only the
run—out
groove with its
increased
lead guides
the shut—off
lever (163)
onto
the dog at a higher
rate so
that the shut—
off lever is
picked up and
moved along
(Fig.
13 b).
As a
result the
shift arm
is brought
into
its neutral
position
the power
switch inter—
rupting
the power
supply.
Simultaneously,
the lift
actuating
lever (146)
coupled to
the shift arm
(155) is
actuated and the to—
nearm (48) lifted.
Adjustment points:
1. Paul
a) Lock
tonearm (48) on its rast.
Paul
should
not be
pressed against segment
(205). The
distance between
pawl (135) and stop (A)
should be 0.1 —
0.2 mm (refer to Fig. 14).
If
necessary, bend shift arm
(146).
b)
Move tonearm (48)
inwards. Shift arm
(146)
should be moved by
cam (135) to its
inner stop. Adjustable with eccentric
pulley
(E) (Fig. 14).
2. Power
Switch
Extract unit plug from
power line. Move
tonearm (48)
to its rest (24). The
power
switch
(106)
should
operate
shortly be—
fore the
tonearm (48) reaches
its rest
(24)
(approx. 3 mm) (Fig. 15). Adjust by
bending the
shut—off lever (158).
3. Segment,
The
shut—off point can be
changed with the
eccentric pulley (S)
on segment (205)
(Refer
to Fig. 16).
