the

lines

of

appear

still.

If

the

lines

move

in

the

direction

of

of

platter,

the

is

high.

If

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

mea-

surement

with

the

light

stroboscope.

companies

brief

frequency

fluc-

tuations

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

can

be

varied

by

about

10

%.

The

variable

speed

control

129/R

19

located

in

the

voltage

divider

is

adjusted

by

turning

the

pitch

control

knob

7.

By

this

the

differential

amplifier

is

altered

and

the

motor

speed

accordingly.

Tonearm

and

Tonearm

Suspension

Th

efeather-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

as

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

49,

the

subsequent

fine

adjustment

by

turning

the

weight.

The

tracking

force

is

adjusted

by

turning

the

graduated

spring

housing

58

incorporating

a

coil

spring.

The

Rotary

knob

54

has

markings

for

a

range

of

adjustment

from

0

to

30

mN

(0

which

permit

accurate

adjustment

of

the

tracking

force.

To

Remove

the

tonearm

or

the

spring

housing

1.

Secure

the

unit

in

a

repair

stand.

Turn

the

rotary

turn

switch

51

to

the

zero

position.

Lock

the

tonearm

48.

Remove

the

counterweight

49.

2.

Turn

the

unit

over.

Remove

the

screening

sheet

140

and

solder

off

the

tonearm

connections

at

the

short

circuiter

137.

Turn

the

52.

The

spring

housing

52

or

the

tonearm

48

may

now

be

changed.

Reassembly

involves

the

reverse

procedure.

Removing

the

tonearm
