The
turntable
platter
and
the
mechanism
are
driven
by
either
a
4
—pole
(131)
or
a
2
—pole
(176)
induction
motor.
Both
motors
have
a
balanced
armature,
polished
bearing
surfaces
and
are
guaranteed
vibration—free.
The
4
—pole
motor
has
the
additional
advantage
of
a
very
small
stray
magnetic
field.
The
speed
of
the
motors
is
constant
over
a
supply
voltage
range
of
10
%.
Deviations
in
speed
depend
on,
and
are
proportional
to,
line
frequency.
Adaptation
of
the
motor
to
50
or
60
Hz
power
is
accomplished
by
changing
the
motor
pulley
(11

The
motor
pulley
is
secured
to
the
motor
shaft
by
a
setscrew.
When
a
pulley
is
replaced
or
ex—
changed,
lt
must
be
set
at
the
correct
height
(see
Figs.
5
and
6).
The
turntable
platter
is
driven
by
the
idler
wheel
(133/140)
which
is
automatically
disen—
gaged
from
the
motor
pulley
when
the
unit
is
shut—off,
in
order
to
protect
its
driving
sur—
face.
Turntable
speeds
of
33
1/3,
45,
78
rpm
are
se—
lected
by
raising
or
lowering
the
idler
wheel
(133/140)
to
the
appropriate
step
on
the
motor
pulley.
When
the
selector
lever
(6)
is
moved,
the
selec—
tor
segment
(105)
rotates.
This
causes
the
lever
(107)
fitted
in
the
slot
of
the
selector
seg—
ment
to
move
in
a
vertical
direction.
The
idler
wheel
(13
3
/
1
40)
mounted
on
the
swinging
arm
(136/144)
is
lifted
off
the
motor
pulley
and
set
down
again
on
the
motor
pulley
step
for
the
adjacent
speed.

Pitch
Control
For
turntable
speeds
33
1/3,
45
and
78
rpm,
the
unit
incorporates
a
voltage—indepen—
dent
pitch
control,
which
permits
a
turn—
table
speed
variation
of
up
to
6
%
(appro—
ximately
one
semitone).
When
the
pitch
control
knob
(7)
is
turned,
the
switch
segment
(105)
and
the
switch
lauer
(107)
attached
to
it
are
moved
up
or
down.
This
vertical
displacement
changes
the
position
of
the
idler
wheel
on
what—
ever
step
of
the
motor
pulley
lt
has
been
placed
on
(by
the
speed
selector),
and,
due
to
the
tapered
shape
of
the
pulley,
effects
approximately
+
3
%
variation
in
speed.

Cam

Contacts

Moving
the
operating

also
releases
the
start
lever
(226),
pulling
lt
towards
the
main
cam
by
means
of
the
tension
spring
(225).
This
causes
coil
spring
to
bring
the
shut—off
lever
(238)
within
range
of
the
main
cam
dog.
Thus
the
shut—off
lever
drives
the
main
cam.
226
To
prevent
malfunctioning,
the
ope—
rating
switch
is
locked
during
the
start
cycle
(that
is,
while
the
main
cam
is
turning).
Just
before
the
main
cam
resches
its
neutral
position
(at
the
end
of
the
change
207
cycle),
the
start
lever
is
pushed
clear
of
the
main
cam
by
the
start
pin
of
the
main
cam.
This
restores
208
the
switch
lauer
and
operating
switch
to
their
original
positions.
267
After
installation
and
also
after
moving
the
changer,
the
unit
should
be
started
with
the
tonearm
locked
on
the
rest.
This
will
automati—
cally
re—adjust
the
shut—off
lever,
which
may
haue
shifted

po—
sition.
Manual
start
When
the
tonearm
(15)
is
suung
in
—
ward
by
hand,
the
paul
on
the
switch
arm
drops
into
a
support
on
the
base
plate,
holding
the
switch
arm
in
this
position
and
the
idler
wheel
(133/140)
in
contact
with
the
platter.
The
slide
(184)
linked
with
the
switch
arm
actuates
the
power
switch
and
sets
the
turn—
table
platter
rotating.
On
reaching
the
run—out
groove,
the
tonearm
automatically
returns
to
its
rest
position
and
the
unit
shuts
itself
off.
(See
shut—off
mechanism,
next
side).
However,
if
the
tonearm
is
lifted
off
the
re—
cord
manually
and
returned
to
the
rest,
the
tabs
of
the
arm
segment
(276)
release
the
pawl.
The
tor—
sion
spring
(220)
then
returns
the
switch
arm
to
its
initial
position,
opening
the
power
switch
and
disen—
gaging
the
idler
wheel.
Stop
switching
When
the
operating
lever
is
moved
to
"stop",
the
starting
lever
(226)
is
pushed
forward.
As
a
result
the
shut—off
linkage
comes
into
contact
with
the
main
cam.
The
swinging
le—
ver
(245)
remains
in
its
stop
po—
sition.
When
the
tonearm
is
on
its
rest
and
the
operating
lauer
is
pushed
to
"stop",
the
operating
lever
must
not
jam.

Muting
switch
To
prevent
the
noises
of
the
change
cycle
from
being
sent
through
the
audio
system,
the
apparatus
is
fit—
ted
with
a
short—circuiting
(muting)
switch
(155).
The
switch
springs
for
both
channels
are
actuated
by
the
main
cam
(242).
In
the
tonearm
rest
position,
the
muting
switch
is
opened.
Record
drop
Insert
the
appropriate
spindle
—
AW
3
for
standard
records
(7
mm
center
hole)
or
AS
12
for
45
rpm
records
(38
mm
center
hole).
Record—drop
is
initiated
by
the
rotation
of
cam,
whose
cam
surface
guides
the
cam
rocker,
pushing
the
change
actuator
stud
and
releasing
a
record
by
means
of
the
automatic
spindle.
The
main
cam
is
designed
so
that
a
record
can
drop
only
when
the
tonearm
is
above
the
tone
—
arm
rest
and
thus
out
of
the
reach
of
the
largest
possible
records
(12"
diameter).
Shut-off
and
change
cycle
The
dog
(M)
on
the
turntable
platter
gear
(PR)
and
the
shut—off
lever
(238)
actuate
both
the
change
cycle
at
the
end
of
the
re—
cord
as
well
as
the
shut—off
after
the
last
record
in
a
stack
is
played.
At
the
end
of
a
record,
the
tonearm
moves
towards
the
center
at
an
accelerated
rate
due
to
the
increased
pitch
of
the
grooves.
This
motion
carries
the
shut—off
lever
(238)
towards
the
dog
by
means
of
the
shut—
off
slide
(278).
The
eccentric
dog
pushes
the
shut—off
lever
(238)
back
at
each
re—
volution
as
long
as
the
tonearm
advance
is
only
one
normal
record
groove.
The
run—out
groove
with
its
steeper
pitch
moves
the
shut—off
lever
against
the
dog
with
greater
force,
engaging
the
shut—off
lever
(238)
and
causing
the
main
cam
(242)
to
be
driven
out
of
its
neutral
position
by
the
turntable
platter
gear.

Shut—off
and
change
functions
are
de—
termined
by
the
position
of
the
cam
follower
lever
(245).
After
every
start
or
record—drop,
the
cam
follower
lever
is
brought
to
its
stop
position
by
the
main
lever
(218)
(longer
end
towards
the
center
of
the
main
cam).
As
the
re—
cord
is
dropped
the
cam
follower
lever
(245)
is
turned
to
its
start
position
by
the
cam
rocker
(214),
so
that
the
tonearm
can
swing
in
toward
the
record
and
be
lowered
on
to
it.
If
there
are
no
more
records
on
the
spindle,
and
the
cam
rocker
cannot
turn
the
cam
follower
lever,
the
lever
remains
in
its
stop
position
and
allows
the
tonearm
to
swing
to
its
rest
position.
When
the
main
cam
(242)
returns
to
its
neutral
position,
the
switch
arm
(221)
drops
into
a
cut—out
in
the
