For the

best

manual turntable

get

a

Pioneer.

The

manual

turntable is rapidly

becoming the

first

choice of

hi

-fi

enthusiasts

everywhe-e.

The

reason

why is quite

simple.

Todaa's

enthusiasts are

more knowledge -

able, more

sophisticated

and

rrore involved

with their

music.

And only

the

manual

turntable can provide

Al

Pioneer,

this

trend comes

as

no

surprse.

We have long recognized

the

superiority

of

the manual turntable.

And

long recognized

a simple fact:

a record

changer

in no

way improves

pe-formance.

I, can

detract from it.

As

a

result, we now

offer

the finest

and

most

complete lme

of

manual turntables

availaole.

Manua

turntables that are

designed

with the

needs

of today's hi -fi

enthusiast

bn mind.

Turntables that are

engineered

for

precision resporse.

When

yOL

get right

down to

it. good

r

cord playing equipment

really has only

two

requirements: uniform rotation

of a

turntable, and accurate

tracing of

a

record

groove

by

a tonearm

and

its cartridge.

P'cneer s engineers

have

long

recog-

nized that

these requirements are best

met

by single

-play

turntables

and

precision

engineered

tenearms.

Our five

new

turntable

systems

mean

you needn't settle for

the

higher wow

and

flutter and

the poorer signal

ratios

(rumble)

of

record changers.

Whether

you've

budgeted $1C0 or $300

for

this

vital

element

of your

high fidelity system.

there's

a

Pioneer turnable tnat outperforms

any

in its price class.

witt typica idler -wheel /pulley

arrangemems normally

found in record

changers. Even chargers equipped

with

synchronous

mo "ors transmit

vibration to

the

turntable

platter.

This is

picked

up

as low -frequency

rumble by the

tonearm and

By driving

the platter

with

a precision-

Their
