Motor

and

Drive

Turntable

and

mechanism

are

driven

by

the

motor

(132)

in

(Fig.

16).

The

shaded-pole

motor

runs

vibration-free

in

radially

elastic

mounts

and

has

an

extremely

low

magnetic

leakage.

The

motor

speed

is

independent

of

voltage,

temperature,

and

load

variations.

lt

can

only

fluctuate

with

the

mains

frequency.

Two

motor

pulleys

adapt

to

the

mains

frequency

of

50

Hz

or

60

Hz

(see

Speed

Selection

To

speed

to

is

adjusted

to

the

one

or

(116)

Nee

Fig.

is

done

by

operating

the

knob

(16)that

will

shift

the

change-over

lever

into

the

desired

speed

Position

through

the

lever

(101)

and

the

spring

lever.

As

long

as

the

platter

is

turned

off,

the

change-over

lever

is

blocked

by

the

bar

(12)

and

the

speed

is

only

pre-selected.

As

soon

as

the

record

player

is

turned

on

and

the

turntable

(7)

starts

running,

the

blocking

bar

(12)

will

release

the

change-over

lever.

The

latter

will

then

shift

the

bell

(15)

to

the

one

step

of

the

motor

pulley

(116)

that

corresponds

to

the

desired

speed.

Turntable

The

turntable

(7)

is

fixed

to

the

turntable

Pull

the

bell

(15)

from

the

pulley

(116)

and

place

it

onto

the

turntable.

Rotate

the

latter

further

until

the

Tone

arm

with

Bearings

The

I

ight-weight

torsion-resistant

metal-tube

tone

arm

has

a

uni-

versal

gimbal

bearing

characterized

by

four

hardened

and

lapped

steel

points

located

in

high-precision

ball

bearings.

The

tone

arm

bearing

friction

is

thus

reduced

to

a

minimum,

namely

less

than

0.1

mN

or

0.01

gr

in

vertical

and

less

than

0.4

mN

or

0.04

gr

in

horizontal

direction

referred

to

the

stylus

point.

This

ensures

particularly

satisfactory

tracking

conditions.

Before

adjusting

the

tracking

force

in

compliance

with

the

pickup

system

used,

the

tone

arm

to

its

balanced

position

while

the

tracking-force

scale

is

in

the

zero

position.

For

coarse

balancing,

shift

the

weight

with

mandrel

(51),

for

fine

balancing,

rotate

the

weight.

This

balancing

weight

will

permit

balancing

of

pickup

systems

that

have

a

weight

(including

mounting

parts)

in

the

range

from

5.5

to

10

g.

The

tracking

force

is

produced

by

tensioning

the

helical

spring

located

in

the

spring

case

(64).

The

latter

has

a

scale

with

marking

points

permitting
