RECORDS.
To
obtain
the
best
results
from
your
records
and
record
changer,
care
should
be
taken
to
see
that
the
records
are
stored
so
that
they
keep
reasonably
fl
at
and
clean.
Dust
or
dirt
in
the
record
grooves
causes
abrasive
action
and
shortens
the
life
of
the
record,
whilst
badly
warped
records
will
give
trouble
in
drop
ping,
poor
reproduction,
and
even
damage
the
pick-up
stylus.

With
a
slight
alteration
the
motor
board
cut
out,
the
"GARRARD"

Record
Changers.
FITTING
TO
CABINET.
First,
the
motor
board
should
be
cut
out
and
drilled
js
shown
on
the
template
enclosed
with
each
changer.
If
the
changer
is
to
replace
one
of
the
"GARRARD"
Models
mentioned
above,
only
the
piece
marked
on
the
left
hand
side
of
the
template
need
be
cut
out.
A
small
clearance
should
be
left
between
the
edges
of
the
unit
plate
and
the
cabinet
sides,
to
allow
the
record
changer
to
fl
oat
freely
when
mounted
on
its
suspension
springs.
Having
opened
the
carton,
remove
the
turntable
found
on
the
top
liner
and
the
box
containing
the
record
spindles,
then,
after
disposing
of
the
side
liners,
care
fully
lift
out
the
changer
by
the
string
loops.
A
bag
containing
the
fi
xing
screws
and
spring
mountings
will
be
found
in
one
corner
of
the
carton.
The
spare
pick
up
head
and
accessories,
if
supplied,
will
be
found
in
u
box
fi
xed
to
the
bottom
liner.
Assemble
the
spring
mountings
to
the
motor
board
as
shown
on
the
tem
plate
and
diagram
1.
Next,
assemble
the
long
fi
xing
screws
to
the
changer
mounting
plate,
fi
tting
the
spring
washer
under
the
nut,
then
assemble
a
nut
on
each
screw
leaving
3/8"
of
thread
below.
Before
placing
the
changer
in
position,
the
fi
nal
switch
off
arm
at
the
rear
of
the
changer,
which
on
un
packing
will
be
found
in
a
downward
position,
should
be
turned
to
a
vertical
position
as
shown
in
the
illustra
tions.
To
do
this,
loosen
the
round
headed
screw
at
the
top
of
the
auto
switch
spindle,
turn
the
arm
to
a
vertical
position
and
re-tighten
the
screw.
The
changer
can
now
be
placed
in
position
on
its
suspension
springs.
Still
using
the
string
loops
for
lifting,
the
changer
should
be
levelled
by
fi
rst
fi

then
placing
a
spirit
level
on
a
record
on
the
turntable,
the
changer
can
be
adjusted
by
raising
it
and
adjusting
the
lower
nuts.
When
level,
the
nuts
should
Page

INSTALLATION
be
assembled
under
the
springs
and
locked
in
position
with
the
lock
nuts.
The
string
loops
may
now
be
removed
and
the
changer
connected
to
the
power
sup
ply
and
pick-up
to
the
reproducer.
It
is
essential
to
use
the
spring
suspension
assem
blies
on
this
model
changer
to
prevent
extraneous
vibration
from
reaching
the
unit.
If
two
record
spindles
are
used,
a
hole
can
be
drilled
in
the
wooden
motor
board
to
take
the
spindle
not
in
use.
If
two
"GARRARD"
pick-up
heads
are
used,
the
plastic
box
in
which
one
of
the
heads
is
supplied,
can
be
screwed
down
into
the
cabinet
to
act
as
a
dust
free
container
for
the
pick-up
head
not
in
use.
If
the
plug-in
feature
is
to
be
used
to
change
pick-ups,
the
cheese
headed
screw
under
the
pick-up
arm
at
rear
of
pick-up
should
be
removed.
This
screw
should
be
replaced
and
tightened
up
for
transit
purposes
only.

Two
plated
wood
screws
are
supplied
for
use
in
clamping
the
record
changer
rigid
to
the

board
for
transit
purposes.
The
small
bakelite
washers
should
be
fi
tted
under
these
screws
to
prevent
marking
the
mounting
plate.
These

every
trace
of
surplus
oil
before
replacing
the
belts.
The
rubber
rim
on
the
intermediate

SPEED.
The
Model
R.C.
80/AC.
Motor
is
arranged
to
give
the
desired
turntable
speed
within
close
tolerances.
Should
the
turntable
run
excessively
fast
or
slow
then
the
motor
pulley
should
be
examined
to
see
if
it
is
the
correct
one
to
suit
the
frequency
of
the
mains
supply.
The
various
motor
pulleys
are
colour
finished
as
follows
to
distinguish
the
three
types:—
Nickel
-
50
cycles.
Brass
-
60
cycles.
Copper
-
40
cycles.
For
use
on
25
cycles
supply,
a
special
motor
and
pulleys
are
required.
The
speed
of
the

and
low
voltage
Models,
is
governor
controlled,
the
governor
being
located
at
the
lower
end
of
the
motor
and
is
screwed
on
to
the
armature
shaft
and
held
in
position
by
a
screw
through
the
governor
collar.
To
adjust
the
speed,
loosen
the
screw
in
the
governor,
and
turn
the
governor
a
very
small
amount
clockwise
to
increase
the
speed,
or
anti-clockwise
to
reduce
it.
Tighten
the
screw
before
running
the
motor
to
check
the
speed.
SPEED
VARIATION.
It
is
essential
that
the
driving
surfaces
of
the
three
brass
pulleys,
the
rubber
tyred
interwheel,
and
the
belts,
should
be
kept
absolutely
free
from
all
oil
or
grease.
This
is
the
fi
rst
point
which
must
be
checked
if
the
turntable
speed
varies
and
the
pulleys,
belts
and
inter-
wheels
should
be
cleaned
with
a
dry
cloth
if
contam
ination
with
oil
is
suspected.
Another
point
to
check
is
that
the
two
belts
run
centrally
on
their
pulleys;
should
they
tend
to
run
off
the
pulley,
try
removing
the
belt
and
turning
it
over.
If
this
does
not
cure
the
trouble,
a
new
belt
should
be
fi
tted.
Also
see
that
the
main
spindle
has
a
small
amount
of
end
play.
To
check
this,
remove
the
turntable
and
grip
the
main
spindle
firmly
lifting
it
up
and
down.
If
no
movement
is
felt,
loosen
the
two
screws
(diagram
10)
which
holds
the
fi
xed
portion
of
the
main
spindle,
raise
the
main
spindle
a
very
small
amount
and
re-tighten
the
screws.
SERVICE
ADJUSTMENTS
NOISE.
Should
the
drive
become
noisy,
fi
rst
see
that
the
screw
holding
the
pulley
to
the
motor
shaft
is
not
touching
the
intermediate
wheel
as
it
revolves.
If
it
is,
raise
the
pulley
by
loosening
the
screw
holding
it
to
the
shaft.
If
the
motor
pulley
is
correct,
then
lubricate
the
pulleys
as
described
under
"Maintenance."
MOTORS.
If
the
motor
fails
to
start
when
the
control
knob
is
turned
to
"Start,"
fi
rst
check
the
power
supply
and
ascertain
if
current
is
reaching
the
motor
terminals.
If
correct,
switch
off
the
mains
supply
and
examine
the
terminal
block
and
see
that
the
leads
and
screws
are
tight,
also
examine
the
switch
contacts
accessible
under
neath.
Clean
and
adjust
if
necessary.
On

PICK-UP.
Two
types
of
needle
are
necessary
for
playing
the
different
types
of
record
and
a
needle
having
a
point
radius
of
.0025"
is
required
for
the
standard
78
r.p.m.
records,
and
one
with
a
point
radius
of
.001"
is
required
for
the
fi
ne
groove
33.1/3
and
45
r.p.m.
records.
To
obviate
needle
changing
either
two
plug-in
pick-up
heads
or
a
turnover
type
of
pick-up
having
two
st&^li
can
be
used.
Care
should
be
taken
that
the
correct
radius
needle
is
used
for
the
type
of
record
to
be
played.
Should
another
type
of
pick-up
be
used
other
than
that
supplied
with
the
unit,
some
adjustment
for
the
difference
in
pick-up
weight
may
be
required.
The
pick-up
weight
adjusting
screw
is
located
under
the
unit
plate
at
the
rear
of
the
pick-up
arm
as
indicated
on
Diagram
10
and
to
adjust
the
pick-up
weight,
the
screw
should
be
pulled
to
bring
the
nut
clear
of
its
bracket
and
the
nut
turned
to
give
either
an
increase
or
decrease
in
spring
tension.
The
maximum
recommended
weight
for
long
playing
records
is
10
grammes.
Page
Should
trouble
be
experienced
with
the
reproduction
from
the
pick-ups,
the
head
should
be
returned
for
examination
to
the
manufacturer
whose
name
or
trade
mark
appears
on
the
cartridge.
Crystal
cartridges
must
not
be
opened
or
the
manu
facturers
will
disclaim
all
responsibility.
Note:
A
continuity
test
cannot
be
carried
out
on
Crystal
Pick-ups
with
an
ohmmeter.
Should
there
be
a
tendency
for
the
pick-up
to
track
incorrectly,
especially
on
the
fi
rst
record,
check
the
pick-up
weight
and
adjust
as
explained
above
if
found
lighter
than
8
grammes.
If
the
pick-up
does
not
run
into
the
record
grooves
after
alighting
on
the
record
edge,
see
that
the
record
changer
is
level
by
placing
a
spirit
level
on
a
record
on
the
turntable.
Also
make
sure
that
the
fl
exible
wire
leading
to
the
pick-up
is
not
twisted
or
held
in
such
a
manner
as
to
prevent
the
free
movement
of
the
pick-up
arm;
also
see
that
the
associated
levers
are
free.
CAUTION.
When
making
any
adjustments
to
the
Pick-up
Arm
it
should
NEVER
on
any
account
be
forced
into
position.
If
the
turntable
is
turned
by
hand
it
should
NOT
be
turned
backwards.
PICK-UP
DROPPING
POSITION.
The
pick-up
arm
dropping
position
is
factory
adjusted
for
optimum
accuracy.
Should
any
minor
adjustment
be
required
rotate
the
screw
accessible
through
the
top
plate
as
shown
in
diagram
11.
Adjust
ment
must
be
made
only
when
the
pick-up
arm
is
in
the

PICK-UP
MUTING
SWITCH.
A
pick-up
muting
switch
is
connected
across
the
pick-up
to
short
circuit
the
pick-up
except
when
the
changer
is
in
the
playing
position.
It
is
important
to
note
that
no
sound
will
be
obtained
from
the
pick-up
by
fl
icking
the
needle
when
the
pick-up
is
on
its
rest.
The
muting
switch
contacts
should
be
closed
except
when
the
changer
is
in
its
playing
position.
Should
this
switch
fail
to
operate,
clean
the
contact
faces,
and
en
sure
that
they
make
and
break
according
to
the
position
of
the
changer
mechanism.
AUTO
TRIP
MECHANISM.
The
auto
trip
mechanism
is
the
velocity
type
and
is
of
a
special
design
to
be
very
light
and
sensitive
in
operation.
It
is
set
to
commence
operation
when
the
needle
reaches
a
1.1/V
radius.
The
trip
operates
by
the
auto
trip
lever
being
raised
by
a
small
cam
attached
to
the
main
spindle
when
the
pick-up
arm
runs
in
on
the
record
run
off
groove.
The
auto
trip
lever,
on
being
lifted,
pushes
a
small
cranked
rod
which
engages
the
clutch.
If
the
auto
trip
fails
to
operate,
it
may
be
caused
by
the
auto
trip
lever
being
too
low
and
it
should
be
raised
by
giving
the
auto
trip
lever
adjusting
screw
(diagram
11)
about
half
a
turn
in
a
clockwise
direction).
RECORD
PLATFORM
ADJUSTMENT.
When
despatched
from
our
Works,
the
record
plat
form
is
set
to
accommodate
records
of
average
dimen
sions.
Occasionally,
however,
records
may
be
found
outside
the
normal
limits.
If
necessary,
therefore,
the
platform
may
be
adjusted
to
take
them.
To
adjust
the
platform
position,
loosen
the
screw
in
the
platform
pivot
collar
(diagram
10)
accessible
from
underneath
the
changer,
rotate
the
pin
by
means
of
the
slot
in
the
end,
until
the
platform
is
in
the
required
position,
then
re-tighten
the
screw.
The
end
of
this
pin
is
eccen
tric,
and
it
is
this
eccentric
which
adjusts
the
platform
position.
Before
fi
nally
tightening
the
screw
after
ad
justing
this
pin,
see
that
a
small
clearance,
about
1/64"
is
left
between
the
eccentric
shoulder
and
the
side
of
the
platform
support.
Separate
adjustment
is
provided
for
the
platform
pawl,
and,
to
set
the
platform
pawl,
fi
rst
set
the
plat
form
lever
in
the
10''
position
and
operate
the
changer
until
the
pawl
is
in
its
forward
position.
It
should
then
be
fl
ush
with
the
edge
of
the
record
platform.
If
it
is
not,
the
nut
locking
the
eccentric
adjustment
for
plat
form
(diagram
10)
should
be
loosened
and
the
eccentric
adjustment
turned
until
the
setting
is
correct,
then
re-
tighten
the
locking
nut.
The
pawl
position
should
now
be
correct
for
all
sizes
of
record.
RECORD
DROPPING.
If
the
changer
fails
to
drop
any
records
other
than
the
45
r.p.m.
type
having
a
large
centre
hole,
fi
rst
make
sure
that
the
records
are
not
badly
warped.
If
they
are
reasonably
fi
at,
the
record
platform
setting
should
be
checked
and
adjustments
made
if
necessary.
Also
check
the
record
spindle
to
see
that
it
is
not
bent
out
of
position
by
laying
it
on
the
template
(diagram
15).
Should
records
fail
to
drop
correctly
when
using
the
large
diameter
record
spindle,
replace
this
spindle
with
the
sloping
one
and
see
that
it
leans
towards
the
record
platform
and
is
exactly
in
line
with
it.
If
this
spindle
is
out
of
position
it
should
be
set
correctly
by
loosening
the
two
screws
(diagram
10)
holding
the
fi
xed
part
of
the
main
spindle
in
position,
turning
the
record
spindle
until
it
leans
towards
the
centre
of
the
record
platform
and
tightening
up
the
screws.
After
tightening
the
screws,
see
that
the
main
spindle
has
a
small
amount
of
end
play
by
first
removing
the
turntable
and
grip
ping
the
main
spindle
fi
rmly,
lift
it
up
and
down.
If
no
end
play
is
felt,
adjust
as
described
under
"Speed
variation"
on
page
7.
On
fi
tting
the
large
spindle
the
records
should
then
drop
correctly.
AUTO
SWITCH.
When
the
last
record
on
the
record
spindle
drops
on
to
the
turntable,
it
allows
the
final
switch
off
arm
to
Page
Eleven
move
inwards
far
enough
to
switch
the
changer
off.
When
any
records
are
on
the
spindle,
the
arm
does
not
move
in
far
enough
to
allow
this
to
happen.
Should
the
changer
fail
to
stop
automatically,
check
the
following
points:—
1
That
the
auto
switch
arm
is
in
vertical
position
as
shown
in
the
illustrations
and
that
its
fixing
screw
is
tight.
2
See
that
the
split
lever
holding
the
spindle
under
neath
the
mounting
plate
is
also
tight—it
is
at
this
point
that
a
slight
adjustment
may
be
made
to
the
position
of
the
knock-off
lever
should
it
for
any
reason
be
forced
out
of
position.
The
auto
switch
catch
lever
(diagram
10)
has
a
friction
pivot
and
if
this
should
become
very
free
it
may
fail
to
hold
the
catch
pin
when
it
should
engage.
If
this
is
so,
remove
the
split
pin
at
the
catch
lever
pivot
and
stretch
the
friction
spring
a
small
amount,
replacing
the
washer
and
split
pin.
