GENERAL
ASSEMBLY
AND
OPERATING
INSTRUCTIONS
If
no
tone
arm
or
cartridge
is
supplied,
refer
to
section
3
in
conjunction
with
the
fitting
instructions
supplied
with
the
tone
arm
and
cartridge
of
your
choice,
Place
the
turntable
on
a
flat
surface
and
remove
packing
pieces
as
necessary.
Place
the
entire
contents
of
the
Oil
Vial
supplied
into
the
bearing
housing.
Should
the
housing
require
subsequent
topping
up,
use
a
light
machine
oil.
Fit
the
platter
complete
with
drive
belt
allowing
the
shaft
to
descend
gently
into
the
bearing
housing.
DO
NOT
USE
FORCE.
With
your
index
finger
through
one
of
the
access
holes
in
the
platter,
hold
the
drive
bell
in
position
ready
to
pass
around
the
motor
pulley.
See
fig.
1.
The
small
pulley
for
33%
RPM,
the
large
pulley
for
45
RPM.
(The
last
sentence
is
not
applicable
on
the
D/C
version
with
electronic
speed
control).
The
platter
and
tone
arm
board
may
require
levelling.
This
is
achieved
by
rotating
the
spring
adjusters
on
the
top
of
the
three
spring
satellites,
anti-
ciockwise
to
raise,
clockwise
to
lower.
To
carry
out
this
operation,
the
platter,
mal
and
tone
arm
are
fitted
in
position.
The
chassis
and
platter
should
bounce
in
a
free
manner.
Should
the
tap
of
the
satellite
touch
the
spring
adjuster
stem,
rotate
the
top
of
the
satellites
whilst
holding
the
spring
adjusters
until
the
assembly
is
quite
free.
Adjust
the
suspension
wilh
the
bell
fitted,
Whilst
adjusting
the
three
springs,
bounce
the
platter
yently
in
the
area
of
the
appropriate
spring
to
ensure
the
suspension
is
entirely
tree.
If
a
spirit
level
is
employed
please
take
into
account
that
the
platter
is
concave
and
therefore
a
correct
reading
may
not
be
obtained.
It
is
normally
sufficient
having
ensured
the
turntabie
is
on
a
level
surface
to
set
the
suspension
by
sighting
the
bottom
of
the
chassis
to
the
base
of
the
turntable.
{If
a
heavy
tone
arm
is
fitted,
the
centre
of
gravity
of
the
assembly
can
be
corrected
by
fitting
mass
rings
which
are
available
through
your
Ariston
agent.
Should
the
turntable
have
a
tendency
to
shed
its
belt,
check
the
motor
is
correctly
seated
in
its
housing,
and
the
pulley
is
parallel
to
the
platter.
Do
not
carry
out
this
operation
whilst
the
turntable
is
connected
ta
the
mains
electricity
supply.
It
is
recommended
that
for
the
purpose
of
bedding
the
bearing
that
the
turntable
be
run
in
for
a
period
of
a
few
hours.
When
the
tone
arm
and
cartridge
are
fitted
and
properly adjusted
the
unit
can
be
cannected
for
operation.
Ensure
the
tone
arm
is
earthed
through
the
amplifier,
and
if
undue
hum
is
detected,
disconnect
the
mains
earth
to
the
turntable
should
your
supply
specify
same,
Ensuring
the
turntable
speed
is
compatable
with
the
record,
the
deck
may
be
switched
on,

FITTING
THE
TONE
ARM
Please
refer
to
the
relevant
manufacturers
instructions
in
all
cases.
The
tone
arm
board
is
removed
for
cutting
and/or
fitting
the
arm
by
with-
drawing
the
retaining
screws
using
the
socket
wrench
supplied
in
the
accessory
pack,
Tone
arm
cables
should
be
fed
through
the
access
hole
to
the
inside
of
the
turntable
base,
where
they
may
be
securely
held
with
the
tle
supplied.
The
tie
should
be
as
tight
as
possible,
and
the
tone
arm
cable
between
the
tie
and
the
tone
arm
should
be
sufficiently
complient
to
move
with
the
turntable
suspension,
generally
for
that
purpose
it
will
be
found
thata
coupleof
inches
of
cable
should
be
allowed
extra
over
the
distance
trom
tone
arm
to
cable
tie.
A
tone
arm
earth
point
is
provided
on
the
sub
chassis.
When
the
tone
arm
is
correctly
fitted,
refer
to
section
2
for
levelling
the
turntable.
When
fitting
a
cartridge
always
adhere
to
the
instructions
provided
by
the
manufacturer,
To
assist
with
fitting
the
cartridge
to
the
Carrier
on
the
tone
arm,
an
alignment
protractor
is
supplied.
Place
the
protractor
over
the
turntable
spindle
and
insert
the
cartridge
stylus
at
the
arrow
point.
The
cartridge
may
then
be
tightened
up
in
that
position.
Dust
on
the
stylus
tip
may
cause
a
deterioration
in
sound
quality,
the
diamond
should
be
cleaned
with
a
soft
brush.
Average
age
of
an
elliptical
stylus
is
somewhere
trom
400
to
600
hours.
It
is
advisable
for
optimum
performance
to
replace
it
periodically.
SPECIAL
INSTRUCTIONS
Motor
Clutch
Assembly.
The
clutch
should
be
lubricated
once
every
three
months
by
placing
a
small
drop
of
light
machine
oil
between
the
pulley
top
and
the
clutch
spring
retaining
washer
Fig,
2
(standard
motor
Not
DC).
The
motor
employed
on
the
standard
motor
ts
a
24
pote
AC
synchronous
type
and
by
its
nature
wil!
generate
a
vibration
or
imperceptible
noise,
neither
wil!
affect
listening
pleasure
since
the
motor
is
totally
isolated.
To
maintain
optimum
performance,
regularly
clean
the
bearing
housing
with
a
cotton
wool
bud
and
top
up with
light
machine
oil,
as
necessary.
The
periphery
of
the
drive
pulley
and
the
belt
should
be
kept
free
from
any
traces
of
oil
or
grease.
Should
they
become
contaminated,
clean
them
with
a
lint
free
cloth
dampened
with
lighter
fuel
or
methylated
or
similar
type
spirit.
The
mat
may
be
cleaned
with
warm
soapy
water.

HINTS
ON
TUNING
Acoustic
Feedback.
Acoustic
Feedback
occurs
when
the
isolation
of
the
pick
up
from
the
loudspeakers
is
inadequate.
Vibrations
from
the
latter
are
received
by
the
pick
up,
turned
into
an
electrical
signal
and
returned
via
the
amplifiers
to
the
loudspeakers,
The
process
is
rapidly
repeated
and
unless
the
equipment
is
switched
off
or
the
volume
control
retarded
the
resulting
signal
level
may
cause
overload
damage
to
the
amplifiers
and
loudspeakers.
If
feedback
is
suspected,
carry
out
a
simple
check
as
follows:
a)
Switch
off
the
turntable
and
place
the
stylus
on
a
stationary
record,
slowly
advance
the
volume
control
up
to
and
a
little
beyond
the
normal
maximum
listening
level.
b)
Hf
and
when
feedback
occurs
it
will
be
heard
as
a
howl
of
rapidly
rising
intensity,
so
be
ready
to
retard
the
volume
control
quickly.
c)
If
the
test
shows
that
feedback
occurs
within
or
close
to
normal
listen-
ing
levels,
attention
should
be
given
to
the
foregoing
points.
d}
Experiment
with
the
positioning
of
the
turntable
should
reveal
marked
differences
in
the
level
of
feedback.
Ensure
the
sub
chassis
is
not
short-
circuited
and
is
quite
free
to
move
both
vertically
and
horizontally.
e}
The
spring
suspension
should
be
adjusted
to
as
low
a
pitch
as
possible.
The
higher
the
platter
and
chassis
sits
on
the
turntable
the
greater
acoustic
feedback
likelyhood.
Mechanical
Noise
There
are
various
areas
which
may
contribute
to
mechanical
noise,
the
likeliest
of
these
are
the
bearings
which
may
require
oil,
the
suspension
which
may
be
short-
circuited
or
the
motor.
Check
the
electrics
and
all
connections,
ensure
the
wiring
is
correct
tor
the
electrical
current
and
frequency.
Wow
The
most
likely
source
of
wow
is
the
drive
belt,
which
may
have
become
contam-
inated
with
oil,
Remove
the
belt
and
clean
it
with
lighter
fuel,
subsequently
dusting
it
with
chalk.
Clean
the
belt
faces
on
both
the
pulley
and
the
hub
with
lighter
fuel.
Rumble
As
the
word
implies,
this
term
describes
the
intermittent
low
frequency
sounds
heard
through
the
loudspeakers
and
can
be
caused
by
foreign
matter
or
imperfect-
ions
in
the
moving
parts
of
theturntable,
The
importance
of
mechanical
excellence
in
these
areas
Cannot
be
overstated
since
the
pick
up
cannot
discriminate
between
the
information
on
the
record
and
unwanted
vibrations
within
the
turntable.
Always
ensure
the
bearing
is
topped
up
with
light
machine
oi].
Ensure
the
sub
chassis
is
decoupled,
