Accurate

setting

of

platter

speeds

33

1/3

and

45

rpm

can

be

checked

during

play

with

the

aid

of

the

stroboscope.

When

the

platter

4

is

rotating

at

exactly

33

1/3

or

45

rpm

the

lines

of

the

stroboscope

appear

to

stand

still.

If

the

lines

move

in

the

direction

of

rotation

of

the

platter,

the

platter

speed

is

too

high.

If

the

lines

move

backvvards,

the

platter

is

rotating

more

slovvly

than

the

nominal

speed.

Adjustment

of

platter

speeds

33

and

Strobe

markings

are

provided

on

the

outer

edge

of

the

platter

for

To

154

remove

machine

screws

156

and

remove

lt

can

happen

that

the

stroboscope

lines

appear

to

move

slightly

although

the

exact

speed

setting

with

stroboscope

stationary

has

not

been

altered.

This

apparent

contradiction

is

explained

by

the

fact

that

the

electronic

central

drive

motor

operates

fully

inde-

pendently

of

line

frequency

whilst

the

only

relatively

accurate

line

frequency

of

the

AC

current

supply

is

used

for

speed

measurement

with

the

light

stroboscope.

The

constantly

table

fluctuations

of

line

frequency

by

±

0.2%

according

to

the

information

of

the

electricity

supply

companies

brief

frequency

fluctuations

up

to

1

%

are

possible

—

only

effect

the

stroboscope

indication

and

can

cause

the

lines

to

"wander"

although

the

platter

speed

is

as

constant

and

absolutely

accurate

as

before.

Pitch

Control

Each

of

the

two

standard

speeds

33

1/3

and

45

rpm

(78

rpm)

can

be

varied

by

about

10

%.

The

variable

speed

control

157/R

located

in

the

voltage

divider

is

adjusted

by

turning

the

pitch

knob

By

this

differential

Tonearm

and

Tonearm

Suspension

The

feather-light,

extremely

torsion

resistant

all-metal

tonearm

is

suspended

in

a

gimbal.

Suspension

is

by

means

of

4

hardened

and

precision

polished

steel

points

which

rest

in

precision

ball

bearings.

Tonearm

bearing

friction

is

thus

reduced

to

a

minimum.

as

related

to

As

a

result,

it

ensures

most

favourable

pick

-up

conditions.

Before

adjusting

the

tracking

force

to

suit

the

built-in

pick

-up

cartridge

the

tonearm

is

balanced

with

the

scale

set

to

zero.

Coarse

adjust-

ment

is

carried

out

by

moving

the

weight

with

the

stem

40,

the

subsequent

fine

adjustment

by

turning

the

weight.

The

tracking

force

is

adjusted

by

turning

the

graduated

rotary

knob

64

incorporating

a

coil

spring.

The

scale

has

markings

for

a

range

of

adjustment

from

0

to

30

mN

(0

3

which

permit

accurate

adjustment

of

the

tracking

force.

are

determined

by
