The
fasteners
used
by
Williams
/
Bally,
and
those
included
in
this
kit,
need
only
be
tightened
enough
to
hold
the
component
in
place
and
prevent
vibration
when
in
use.
Please
allow
approximately
30
minutes
to
install.
This
kit
requires
no
permanent
modification
to
the
machine.
You
may
want
to
take
photos
of
your
particular
machine
in
the
event
you
wish
to
accurately
restore
it
to
its’
original
configuration.
Step
One
–
Machine
Preparation.
Make
sure
you
have
adequate
space
available
to
access
the
front
and
both
sides
of
the
machine.
Make
sure
the
machine
is
turned
off
and
unplugged
from
its’
power
source.
To
install
this
kit
you
will
need
to
remove
the
translite
to
access
the
back
box
speakers,
speaker
connections,
and
to
mount
the
volume
control.
Woofer
installation
requires
access
to
the
inside
of
the
base
cabinet.
If
you
are
not
familiar
with
the
procedures
to
access
these
areas,
i.e.
removal
of
the
translite,
removal
of
the
playfield
glass,
and
raising
the
playfield
to
the
service
position;
please
refer
to
the
Williams
/
Bally
owners’
manual.
Step
Two
‐
Back
‐
box
speaker
removal.
First,
remove
the
translite.
For
safety,
I
would
find
a
towel
to
drape
across
the
machine
for
the
speaker/display
panel
to
rest
on.
This
will
protect
both
your
speaker/display
panel
and
the
side
rails
from
getting
scratched.
Lay
the
panel
on
its
front,
spanning
across
the
side
rails.
See
photo.
Carefully
examine
the
existing
installation
of
the
back
box
speakers.
Note
the
routing
of
the
stock
wiring.
The
green
wire
going
to
one
of
the
fasteners
holding
the
existing
back
box
speakers
is
a
ground
wire
which
must
be
re
‐
attached
when
the
new
speakers
are
installed.
