Maintenance

The

motor

and

intermediate

wheel

bearings

are

of

the

oil

retaining

type

and

rarely

need

lubricating.

When

the

need

for

oil

is

apparent,

hold

the

intermediate

wheel

away

from

contact

with

the

motor

pulley

and

lubricate

the

top

motor

bearing

with

a

fine

grade

of

machine

oil;

that

used

for

sewing

machines

is

suitable.

Also

lubricate

the

intermediate

wheel

bearing,

the

bearing

in

the

top

of

the

turntable

spindle

and,

very

occasionally,

the

bottom

motor

bearing.

Remove

all

traces

of

surplus

oil

before

running

and

make

sure

that

the

motor

pulley,

running

surface

of

the

intermediate

wheel

and

inside

of

turntable

rim

are

clean

and

free

from

oil.

Oiling

points

are

shown

on

diagrams

two

and

six.

To

remove

turntable

to

gain

access

to

the

oiling

points,

first

remove

the

turntable

mat

by

pulling

it

off

the

centre

boss,

then

lift

off

the

outer

turntable.

Next

remove

the

nameplate

in

the

centre

by

levering

it

up-

ward

with

a

screwdriver

or

penknife

in

one

of

the

slots.

The

retaining

clip

is

then

accessible

and

should

be

removed.

Remove

the

turntable,

with

foam

mat

attached,

by

lifting

with

the

fingers,

applying

equal

pres-

sure

on

diametrically

opposite

sides.

Should

the

turntable

be

difficult

to

remove

place

the

short

manual

record

spindle

in

position

and,

while

lift-

ing

the

turntable

as

described,

get

an

assistant

to

give

the

top

of

the

record

spindle

a

tap

with

a

piece

of

wood,

such

as

the

handle

of

a

screwdriver.

The

turntable

should

be

replaced

with

unit

in

switched

off

position,

instructions

for

its

reassembly

is

given

on

page

six.

Installation

Dimensions

The

Type

A

Auto

Turntable

is

122”

back

to

front*®

(see

under)

by

23”

below

and

53”

above

top

of

motor

board.

An

additional

4”

on

the

height

and

all

round

the

edges

are

required

to

permit

unit

to

freely

float

on

its

suspension

springs.

*An

extra

13”

is

also

required

at

rear

of

pickup

arm

and

on

right-hand

side

to

allow

clearance

for

counterbalance

weight,

see

template.

Fitting

The

motor

board

should

be

drilled

and

cut

out

to

the

template

supplied.

Do

not

moisten

the

template

as

it

may

distort,

but

fix

it

with

self-adhesive

tape.

The

spring

suspensions

assembled

to

the

unit

are

designed

for

boards

3”

thick

or

less.

Should

the

board

be

thicker

than

3”,

the

four

holes

should

be

recessed

underneath

11”

diameter

to

give

a

maximum

of

}”

thickness.

If

not

already

fitted,

connect

a

power

supply

lead

to

the

connecting

block,

diagram

six.

The

motor

should

be

earthed

by

con-

necting

a

lead

from

a

good

earthing

point

to

the

earthing

tag

located

at

rear

of

plate

holding

connecting

block,

also

connect

the

audio

leads

from

the

amplifier

to

the

pickup

strip

as

shown

on

diagrams

three

and

four.

Place

and

to

maintain

the

full

advantage

of

this,

marking

is

pro-

vided

to

enable

it

to

be

Before

shipping,

the

transit

screws

(copper

plated

for

identification)

should

be

used

to

hold

the

unit

firmly

to

the

motor

board.

Use

the

These

screws

must

be

Pickup

and

Arm

Unpack

the

pickup

arm

counterbalance

weight

and

slide

it

on

rear

of

arm,

as

shown

on

diagram

two,

tighten

the

screw

to

hold

it

in

position.

If

the

unit

is

of

your

choice

shouid

be

fitted

by

means

of

the

instructions

and

hard-

ware

supplied

with

the

pickup

is

in

position

see

that

the

pointer

indicating

the

stylus

pressure

on

side

of

arm

is

in

the

rear

position

with

the

released.

If

not,

loosen

the

screw

under

the

arm,

slide

as

it

will

go

and

tighten

the

screw.

Next

adjust

the

position

of

the

counterbalance

weight

on

rear

of

arm

by

loosening

the

screw

holding

it

and

sliding

the

weight

along

the

arm

until

the

point

of

Voltage

and

F

requency

The

Garrard

Auto

Turntable

Type

A

is

a

dual

voltage

model,

suit-

able

for

100/130

volts

and

200/250

A.C.

It

may

be

used

on

50

or

60

cycles

according

to

the

size

of

motor

pulley

supplied.

The

motor

pulleys

are

colour-finished

for

easy

identification

Nickel

for

50

and

Brass

for

60

cycle

power

supply.

When

ordered

for

use

on

either

of

these

frequencies

the

correct

pulley

will

be

fitted.

}

The

motor

should

be

earthed

by

connecting

a

lead

from

the

earthing

tag,

located

on

rear

of

bracket

holding

the

connecting

block,

to

a

good

earthing

point,

diagram

six.

If

the

unit

is

connected

to

an

amplifier

with

its

Wiring

not

isolated

from

the

power

supply,

isolating

components,

condensers

or

trans-

formers

should

be

incorporated

in

the

pickup

circuit,

otherwise

the

pickup

circuit

can

become

live.

If

in

doubt,

consult

your

radio

dealer.

Speed

The

Garrard

Type

A

Auto

Turntable

is

designed

to

give

the

desired

turntable

speed

within

close

tolerances.

Should,

however,

the

turn-

table

run

excessively

fast

or

slow,

the

motor

pulley

may

not

be

correct

for

the

frequency

of

the

power

supply.

These

pulleys

are

colour

finished

for

identification,

Nickel

for

50

and

Brass

for

60

cycles.

To

gain

access

to

the

motor

pulley,

remove

the

turntable

as

described

on

page

five

under

“Maintenance”.

Should

the

speed

vary

during

playing,

examine

the

motor

pulleys,

rubber

intermediate

wheel

and

inside

of

turntable

rim

for

traces

of

oil,

wipe

thoroughly

with

a

clean

cloth.

Check

that

the

motor

pulley

is

in

its

correct

position

on

the

and

that

both

screws

are

tight.

See

that

the

intermediate

wheel

runs

in

the

centre

of

the

appropriate

pulley

step

and

does

not

rub

on

the

side

of

the

adjacent

step.

If

necessary,

loosen

the

screws

holding

the

pulley

to

the

shaft

and

move

pulley

to

its

correct

position.

Motors

If

the
