The
speed
is
selected
by
means
of
a
speed
selec
tor knob
(6)
that
is rigidly
united
with
the
speed
selector
cam
(86). The
speed
selector
cam
(86)
moves
the
idler
wheel
support
(83)
to
the
correct
height
with
respect to
the
motor
pulley
(125).
Speed
precision
control
This
adjustment
is
possible
at any
speed.
A knurled
knob
(8)
provided below
the
speed
selector
knob
(6)
moves the
idler
wheel
support
(83).
The
four
steps
of
the
step
pulley
(125)
corresponding
to the
four
turntable
speeds
are
tapered.
When
adjusting
the
precise
speed
±
3
%,
the
idler wheel
(61) must
engage in
the
middle
of
the
step
pulley
(125).
The
knurled
knob
(8)
has
a
red mark
that
must be
positioned
exactly midway
between
+
and
—
when
making
this
adjustment.
Control lever
Movement
of
the
control
lever
(32)
operates
the
starting
lever
(197)
through
a
brass
switching
roller
(176)
that is mounted
on
the
control
lever
bottom
assembly (175).
The
starting
lever
(197)
frees the
ON/OFF
switch
(179)
so
that the
motor
(126) is
connected
to
power
and
starts
running.
The
idler
wheel
(61)
is, at
the
same
time,
pressed
against
the
drive
shaft
(125)
of
the
motor
(126)
and
against
the
inside
rim
of
the
turntable.
The
control lever
(32)
releases
the spring-loaded
ratchet
lever
(192)
which
is
thus
allowed
to
advance
the
reject
lever.
The
cam
of
the
spinning
turntable
(1)
engages
the
ad
vanced
tip
of the
reject
lever.
The
control
cam
(128)
is
thereby
turned
to such
an extent that
the
pinion
of the turntable
meshes
with
the toothing
of
the
control
cam
(128).
Following
one
control
operation,
all
the
control
elements
are
moved
to
the
position
required
for
the
following
function,
Pick-up
arm
movement
The
rising
portion
of
the
cam
track
of
the
control
cam
(128)
causes
the
feed
lever
(150)
to lift
the
pick-up
arm
(10)
by
means
of
the
lift
rod
(57).
At
the
same
time,
the
pick-up
arm
(10)
is
frictionally
engaged
and
is
then
moved
by
the
succeeding
horizontal
movement
of
the feed
lever
(150).
Down
the
descending

Record dropping
The control cam (128)
operates
the
drop lever
(108)
for
the
control
of the automatic
record spindle
(4).
As
the
push rod
extension
(96)
is pulled
down,
the
supporting
levers
are
retracted
to
release
the
record
which
is
thus dropped
on
the rotating
turn
table.
Record
size
discrimination
The upper
locating
lever
(42)
as controlled
by
the
control
cam (128) is
moved
inside
the
operating
range
of
a
feeler
pin
(34)
rotating
with
the
turntable.
Depending
on the
size
of
the record, the
feeler
pin
(34)
is
pressed
down
to
a
greater
or smaller
extent.
The
level
of that
pin controls
the
different
distance
by which
the locating
lever
(42)
is
restored
for
the
inward
movement
of the
pick-up
arm
(10)
to
its
position
above
a 7”
or 10”
record.
In the
presence
of
a
12”
record,
the
upward
movement
of
the
sens
ing
lever
(154)
as released by
the
control
cam (128)
is limited.
The
upper
locating
lever
(42) is
locked
during
its return
movement
and thus
reduces
the
inward
movement
of the
pick-up
arm
(10)
to
the
starting
grooves
of
the
12
record
Tripping
As
the
pick-up arm
(10)
moves
towards
the
center
of
the record,
the
trip
link
(186)
supported
on
the
pick-up
arm locator
segment
(184)
impells
the
reject
lever
towards
the
turntable
cam.
After the
stylus
has
reached
a
record diameter
of about
423/32”
(120
mm),
the
reject
lever
touches
the
rotat
ing
cam
for the
first time
and
is
repelled
by the
latter
until the
lead-out groove
with
its
higher
pitch
causes
the reject
lever
to
be
engaged by the
cam
of
the turntable
(1),

Automatic
shut-off
After
the
last
record
has
been
played,
the
pick-up
arm
(10>
returns
to
the
pick-up arm
rest
(30>
and
is
not moved
inward
again.
Because
of
the
absence
of
records,
the
final
shut-off
is
initiated
inside
the
automatic
record
spindle
(4).
This
has
the effect
that the stop
switch
(129)
on the
control
cam
(128)
is
no
longer
operated
by
the
shut-off lever
(113).
Due to
the
unchanged
position
of
the
stop
switch
(129),
the
feed
lever
(150)
is
directed
into
the
shut
off
track
of
the
control cam
(128).
In
the
course
of
the
shut-off
procedure,
the
idler
wheel
(61)
is
with
drawn
from
the motor
pulley
(125)
and
the
inside
rim
of
the
turntable
and
the
record
player
is
dis
connected
from
mains power.
Automatic
single-play
By
inserting
the
single-play
spindle
(5),
the
auto
matic
turntable
becomes
a
fully
automatic
single-
play
turntable.
Depending
on
the
size
of
the
re
cord,
the
pick-up
arm
lands
within
the
standardized
area
of
the lead-in
groove
as
in
the
case of changer
operation.

actuates
the
cueing

(159)
and
thus
reduces
the
height
of
the
pick-up arm.
The
centering
portion
of
the
single-play spindle
rotates
with
the
turntable
(1)
and thus
avoids
any
friction
at
the
record.

so
that
no
additional

Pick-up
arm
The pick-up
arm
is
balanced
by
means
of
the
counterweight
by
radial
movement
of
the latter
on
the
tail
end
of
the
pick-up
arm. The
pick-up
with
the
slide
carrier
must be
incorporated
for
this
adjust
ment.
For
protecting
the
pick-up
arm
bearing
against
shocks and
for absorbing
vibrations,
the
counter
weight
is
elastically
mounted
to
the
pick-up
arm
tube. The
tracking
behaviour
of
the
pick-up arm
and thus the
most
important
quality
characteristic
of
the
pick-up
arm is
determined
by its bearings.
To
assure
the minimum
possible
friction
for
the
horizontal movement
of
the
pick-up
arm, we
have,
therefore,
used
a
superfine
twin
ball-bearing,
the
brasses
of
which have
an
extra-fine
finish.
The
bearing
permitting
the
vertical movement
of
the
pick-up
arm
also
consists
of
two
superfine
ball-
bearings
with
a
specially treated
surface.
The
very
small
frictional
forces of
the
pick-up
arm
are
of
extreme
importance
for
the
antiskating
device.
Dependability
features
If
the
horizontal
movement
of
the pick-up arm
(10)
is
interfered
with
or
if
the
unit
is
started
while
the
pick-up arm
(10)
is still
locked,
this
cannot
affect
the operation
of the
unit
because
the pick-up
arm
(10)
is
connected
to
the
operating
mechanism
for
the
horizontal
movements
by
means
of
a slipping
clutch (184). The
pick-up arm
lifting
elements
are
resilient
to
permit
the
lifted pick-up
arm
(10)
to be
pressed down
without
allowing any
permanent
deformation
to
interfere
with
the
proper
operation
of
the
unit.
When
the
unit
is
started
without
a record
on
the
turntable,
the
pick-up arm
(10)
remains
on its
rest.
The
feeler pin
(34)
and
the
sensing
lever
(154)
remain
unaffected
by
a
recording
during
the
sens
ing operation. Since the
feeler pin
maintains
its
position,
the
lower
locating
lever (151)
is not
repelled
so
that the
pick-up arm
is
prevented
from
moving
in
on
the
record.
Chassis
plate
The
chassis
plate
is
a
laminated board.
A 032”
(08
mm)
thick aluminium
sheet
is
pressed
upon the
.06” (1.5
mm)
steel
plate,
using
a
heat-sensitive
adhesive
at
a
high
temperature.
This
ensures
a
high degree
of
rigidity
and minimizes

After

The

has
been locked.
Antiskating device
Since the
pick-up arm
is
not
infinitely long and
since
the pick-up head
is
arranged
to form
a
certain
angle
with the
pick-up
arm
tube,
a
small
force
results
at
the pick-up arm
that
tries to
impeil
the
pick-up arm
towards
the
center of the
record.
This
skating
force, as
t is called,
has
the effect that
the
stylus
exerts more pressure
on
the inside
edge
than
on the
outside
edge of the
record
groove.
The skating force
is a
function of the stylus
pres
sure, the
stylus
tip radius and
the
frictional
con
ditions existing
between the
stylus
and the
record.
The
antiskating
adjustment
is
made by adjusting
the
stylus force, This
is
done by
means
of
a
spring
in axial alignment
with the
pick-up arm. The
anti-
skating device
is controlled by
means of
a control
knob.
Corrections are needed
where
different
stylus tip
radii, elliptical needles
or wet
playback
are
used.

Pick-up head
When
mounting
pick-ups
on
the pick-up
head
(7) it
must be
kept in mind
that the
playback
needle
must
be
in
an accurately
defined
geometric
position.
The
mounting
gauge
(26)
supplied with
turntables
without
pick-up
makes
it
possible to check
the pick
up
for correct
position.
Mounting
pick-ups
on the
pick-up
head
(only
applicable
to
units
without
pick-up)
To
mount
a pick-up,
please
proceed
as
follows:
1)
Turn
the
rotary
knob
for the tracking
angle
ad
justment
(6)
to position
I Then
mount
the
pick
up
by
means of
the screws
(22) and
spacer
rollers
included
in the accessories so on the
pick-up
retaining
plate (27)
that the needle
of the
pick-up
is exactly
in the
center
of
the two
inter
secting
lines
of
the
mounting
gauge (26)
that
has
been
slipped over
the guide
grooves
of
the
pick-up
head.
In this
position,
the needle
should
just
touch the
inside surface
of the
mounting
gauge.
Choose
the size of
the screws
and
of
the
spacer
rollers
as required
for
the
pick-up.
2)
Loosen the
retaining screws
(22)
of the
pick-up
up
once
more
a
little
and move
the
pick-up
side-
wards
until the needle
agrees
with the
longi
tudinal
line. Tighten
the
retaining
screws
again.
3)
For
the
longitudinal
movement
of
the pick-up,
loosen
the screw
(24)
and
shift the
pick-up
until
the
needle
coincides
exactly
with the
cross-line
of
the
two intersecting
lines on
the mounting
gauge
(26). Tighten
the
screw
again.
The
pick-up
is now
accurately
adjusted
and
you
have the
guarantee
that
the needle
will always
land
in
the starting
groove
of
the
record
in
automatic
operation.
The slide-in
pick-up head
is
equipped
with a 5-pole
connector.
Both
the
two
chassis connections
of the
channels
and also
the
grounds
of the

In
the case of
a regular
model,
I, e. when
the

in the
pick-up head
is
connected
to a

pin the leads
(25) should
be
connected
as follows
Tracking
check
To
prevent geometric
playback
errors,
the horizon
tal
ditance
of the

tip
must
also be correctly
adjusted.
In the
PE

this
is the
case
when the

the customer,
adjustment
to
the

Instructions
When
the
record changer
is
assembled,
all
sliding
and bearing
points
are
sufficiently
packed
with
lubricants,
Relubrication
of
these
points
is
required
after
about
1000 operating
hours
in
normal
opera
tion.
The
following
oils
and
greases
should
be
used
for
this
purpose:

It is
important
that
no
oil or grease
be allowed
to
get
to the
friction faces
of the
idler
wheel,
of the
turntable
and
the
drive
pulley.
Lubricants other
than
those recommended by
us are liable
to under
go
chemical decomposition.
We
would,
therefore,
advise you
to
use
only
the
lubricants
recommended
by
us.
