Parts
Mount
the
four
octal
sockets
with
#4
screws,
nuts,
and
lockwashers
(the
small-
est
screws
supplied).
Note
that
there
is
a
small
slot
or
keyway
in
the
center
hole
of
each
socket;
be
sure
in
each
instance
that
this
keyway
is
properly
oriented
as
shown
in
the
pictorial
diagrams.
Insert
the
screws from
the
top
of
the
chassis
and
mount
the
sockets
from
the
inside.
Fasten
each
screw
with
a
nut
and
lockwasher.
Mount
the
input
socket
from
the
inside
of
the
chassis
using
#4
screws,
nuts,
and
lockwashers.
Using
#4
hardware,
mount
the
four screw
terminal
strip
on
the
outside of
the
chassis.
Mount
the
slide
switch
from
the
inside
with
#4 screws.
Nuts
and
lockwashers
are
not
necessary
in
this
instance.
Follow
the
position
of
the
connecting
lugs in
the
pictorial.
Mount
the
fuse
post
with
the
special
nut
provided.
The
rubber
bushing
goes
on
the
outside
of
the
chassis.
Note
that
there
is
only
one
correct
way
for
the
post
to
be
mounted.
Insert
the
rubber
grommet
in
the
%"
hole
at
the
end
of
the
chassis.
Mount
the
10,000
ohm
bias
potentiometer
in
the
%" hole
near
the
pair
of
octal
sockets.
Put
the
lockwasher
on
the
shaft,
insert
the
control
in
the
hole
and
fasten
at
the
top
of chassis
with
the
%"
nut.
Note
orientation
of
connecting
lugs.
Mount
the
five lug
terminal
strip
and
the
solder
lug
at
the
center
of
the
chassis.
Insert
a #4 screw from
the
outside.
Place
the
terminal
strip
over
the
screw,
then
the
small
solder
lug,
then
the
#4
nut.
With
#4
hardware,
mount
the
cable
clamp
loosely
near
the
single
octal
socket.
Feed
all
the
wires
of
the
power
trans-
former, PA-135,
through
the
single
hole
provided.
Fasten
the
transformer
in
place
with
two
#8
screws in
the
holes
nearest
the
front
of
the
chassis
using
#8
lockwashers
and
nut<>.
Now,
from
the
bottom,
place
the
choke
over
the
remain-
ing
two
transformer
mounting
holes
and
fastcn
both
