Defect
After
adjustment of the tonearm set—down
point for 30 cm records the set—down point
for 17.5 cm
records is incorrect.
Cause
Eccentric pin (E) of contact
piece (230) out
of
adjustment.
Remedy
Adjust tonearm set—down
point by turning
eccentric pin
Defece
Horizontal tonearm movement shows resist—
ance
during set—down.
Cause
Adjustment
sleeve or set screw
out of ad—
justment.
Remedy
Rotate cam (144) from its neutral position
until main lever (154) lifts the tonearm
completely.
Turn adjusting sleeve (211) so that the
bottom edge of the cartridge head is 3 mm
above the top edge of the
tonearm rest, the
tonearm being unlocked. Then, turn set screw
(62) so that there is a play of approxima—
tely 0.1 mm between stud and contact face
of tonearm (measured at tonearm head approx.
0.5
mm).
(Fig.
23).
Ddece
Tonearm moves with
tracking force and
anti—skating scale
in 0 position
outwards
b inwards
During
automatic Oper—
ation of tonearm
disturbing noises
are perceptible.
No
reproduction. The
short circuit of the
pick —up leads is no
langer being elimi—
nated.
Motor does not shut
off when tonearm sets
down on rest.
Acoustic Feedback
Cause
a) Anti—skating de—
vice out of ad—
justment
b)
Excessively tight
tonearm
leads
produce
a torque
Short sircuiter
out
of
adjustment. The
distances
between
the
slide springs
and
the short cir—
cuit
strips on the
short
circuiter are
excessive.
Distance between the
slide springs and
the short
circuit
strips on the
short
circuiter
is absent
or insufficient.
Suppression
capaci—
tor
(in power
switch)
is defective
(short
circuit).
a)
Chassis compo—
nents (e.g. also
connecting
leads)
are rubbing on
outout.
b) Connecting
leads
are too
tight.

Remedy
a) Adjust
skating lever so that skating
spring acts exactly at the tonearm pivot
b) Loosen tonearm leads.
By bending the short circuiter strips. Ad—
justment is correct when, with the camwheel
in neutral position, the distance between
the slide springs and the short circuit
strips on the short circuiter is
approxima—
tely 0.5
mm.
Spray contact springs
with pre—
servative (e.g. Kontakt 61) and check ad—
justment of short circuit strips.
By adjusting the
short circuit strips. Ad—
justment is correct when, with the camwheel
in neutral
position, the distance between
the slide springs and the short circuit
strips on the
short circuiter is approxima—
tely 0.5
mm.
Replace suppression capacitor in power switch
with neu
component.
a)
Line
up
cutout
according to
instructions
supplied with unit. Move leads.
b) Slacken or
lengthen cable
