and

Maintenance

Speed

Adjustment

You

can

adjust

the

speed

of

the

ST8

precisely by means

of

the

33-1/3

and

45

rpm

speed

controls.

Play

a

record

and

observe

the

stroboscope

markings

in

the

stroboscope

window.

If

the

markings

appear

to

be

moving

to

the

right

(too

slow)

turn

the

appropriate

speed

control

(33-1/3

or

45

rpm)

clockwise.

If

the

markings

are

moving

to

the

left,

turn

the

control

counterclockwise.

You

can

also

fine-tune

the

speed

of

the

ST8

so

that

you

can

play

along

with

your

records

and

have

the

reproduced

music

in

tune

with

your

musical

instrument.

Turning

the

appropriate

speed

control

clockwise

increases

the

pitch

of

the

reproduced

music,

while

turning

the

control

counterclockwise

decreases

the

pitch.

Tracking

Adjustment

A

tracking

adjustment

has

been

preset

at

the

factory.

However,

some

sl

ippage

may

take

place

during

shipment.

You

can

ensure

precise

tangential

tracking

by

following

this

procedure:

1.

Make

sure

the

tracking

shaft

is

rotating

(black

cylinder,

visible

through

opening

in

top

plate).

If

it is

not,

rotate the

platter

one

revolution

in

reverse

direction,

then

try

again.

2.

Play

a

33-1/3

rpm

record.

3.

Allow the

arm

to

track

across

about

one

inch

of

the

record.

4.

Observe

whether

the

arm

is

leading

or

lagging

the

notch

in

the

restrictor

arm.

If

the

arm

is

lined

up

perfectly

with

the

notch,

and

the

arm

cues

straight

up,

no

further

adjustment

is

necessary.

If

not,

refer

to

Step

5.

5.

Move

cue

lever

to

rear.

The

tracking adjustment

knob

is

located

on

the

rear

of

the

carriage.

If

the

tonearm

is

leading

the

notch

in

the

restrictor

arm

—

tending

toward

the

center

of

the

record

—turn

the

adjustment

knob

sl

ightly

clockwise

as

viewed

from

the

rear.

If

the

tonearm

is

lagging

the

notch

tending

toward

the

beginning

of

the

record

—turn

the

knob

sl

ightly

counterclockwise.

Repeat

the

procedure

until

the

tonearm

remains

closely

lined

up

with

the

notch

as

it

tracks

across

a

complete

record.

Cleaning

the

ST8

ST8

maintenance

is

limited

to

periodic

cleaning

and

dusting.

In

particular,

clean-

ing

the

slide

rod

and

tracking

shaft

near

the

back

of

the

turntable

wil

l

help

keep

your

ST8

peak

operating

condition.

Move

the

cue

lever

to

the

rear.

Using

the

control

arm

grip,

move

the

carriage

to

the

left

end

of

its

travel

to

expose

the

stainless

steel

slide

rod.

Clean

the

slide

rod

with

a

soft

cloth

or

cotton

swab moistened

with

isopropyl

alcohol.

Using

the

control

arm

grip,

move

the

carriage

to

the

right

end

of

its

travel.

The

tracking

shaft

is

the

black

cylinder

visible

through

the

carriage

opening.

(You

can

see

the

tracking

shaft

turn

when

the

platter

rotates.]

Clean

the

tracking

shaft

as

you

did

the

slide

rod.

The

stainless

steel

parts

of

the

turntable

(for

example,

the

slide

may

be

similarly

cleaned.

Remove

dust

using

the

soft

brush

attachment

of

a

Never

apply

alcohol,

or

abrasives

to

the
