PREPARATION
OF
THE CABINET
1* Two templates
are provided, one for
the cabinet
shelf and
the other for the cabinet
panel*
The
shelf
template
is used to locate exactly
two holes that are
to be drilled
in
the
shelf* The
panel template
is
used
to
locate
exactly the required
rectangular
cut-out. The
two templates
must be used together
as
indicated, as
there is an exact
relationship
between
the locations
of the
shelf
holes and panel
cut-out.
2. To
use the shelf template,
cut it
or fold it back
exactly
along
the dashed line that
corresponds
to the
panelthickness*
Remove the shelf from
the cabinet
and line
up
this dashed
line on the template
with the
front edge
of the shelf,
positioning
it
also
along
the
edge to leave
at least
1
1/2"
clearance
on each
side*
Tape the
template
in
position
and
use a center
punch
to mark the centers of
the two holes
to be drilled*
[f
the shelf
can
not be removed, place
the template
in a
similar
manner on the top
side of
the shelf
if there is
room to drill
from the
top
side,
or on the
under side
of
shelf
if there
is
only
room
to drill from
the under side.
If the template
is
used on the underside of
the
shelf,
mark
the rear
edge of the shelf at
the points
where
the
extended heavy
lines on
the template hit
the rear shelf
edge.
After the holes are
center-punched,
remove the
template
and drill carefully
through the
punched cen-
ters to a
diameter of 1/4".
If the shelf
has
been re-
moved
for the drilling
operation,
now re-mount
It.
Finally, replace
the shelf-template
in exactly
its former
position
on the top-side of
the shelf and tape
it down*
If
the shelf template
had been
used on the underside
of
a
stationary shelf,
now
place
it on the top-side
of
the
shelf using the marks
on
the rear edge of
the
shelf pre-
viously made.
(In
the latter case, accuracy
may
be
improved
by cutting
the two holes out
of the shelf-
template
with
a
razor blade and
then
lining
up the
holes in
the shelf template
with
the holes
in
the
shelf).
3. To
use the panel
template,
cut it
or fold It back
exactly a
long the dashed
line. This dashed
line
cor-
responds
to the
junction
of the top side of
the
cabinet
shelf
and
the interior side of the wood
panel*
Position
the panel template
against the
interior side of
the
wood
pane! so
that
the
dashed
line rests against
the shelf
and
the two
heavy
vertical
lines
in
the panel
template
meet
with the two
heavy
horizontal lines
in
the
shelf
tem-
plates. Tape
the panel
template down and
use a center-
punch to make the
centers of
the
four
3/8"
holes
in the
four corners
of
the rectangular
cut-out
shown on
the
template.
Now remove
both templates and
drill
care-
fully
through each
of
the four
punched
centers
to a
PAGE 3
hole
diameter
of
3/8".
On
the front
side of
the
wood
p'anel
scribe a
rectangle
externally
tangential
to
the
four drilled
holes*
Check
the
height
and
width of
the
rectangle
against
the panel template
dimensions*
These
dimensions should
not be exceeded*
Now
carefully
cut out the
rectangle
with a
sabre saw, using a
small-
blade
to start
accurately
in the
3/8"
holes. After
the
cutting
operation,
any
rough spots or
excess material
along
the
edges
of the
cut-out may
be removed with a
file*
Finally,
brush or
blow out all
chips and sawdust.
MOUNTING
THE
UNIT
1. Insert
the unit from
the rear
of the cabinet,
care-
fully
guiding
the
controls through
the panel
cut-out.
Center
the
unit Inthe
cut-out and
re-mount the panel
with the four screws
previously removed.
2.
From
the rear of
the cabinet,
pull the
amplifier
toward
you gently,
until the front
panel is
flush against
the
wood panel.
3.
Now place
5/8"
flat
washers
against
the heads
of
the two
*8
x
1
3/4"
screws
provided
and
insert
them
from the
bottom
side of
the shelf
into the
two
holes
drilled
previously.
It may
be necessary
to
shift the
unit
slightly to
the left
or right
in
order
to afford
clear
ac-
cess for
the screws.
When both
screws
have caught,
tighten them
to secure
the
unit to
the shelf*
4. Replace
the
knobs
previously
removed
on
the con-
trol shafts.
