Connect
the
free
end
of the
large
red
wire,
coming
from
hole
12V/IN
of
the
T/R
circuit
board,
to
switch
SW2
lug
2
(NS).
(
)
Bend the
solder
lugs
at
controls
R3/SW2
and
R2
away
from
the
chassis
enough
to
allow
you
to
route
wires
between
them
and
the
chassis
in the
following
steps.
(
)
Connect
the
free
end
of the
red
wire,
coming
from
hole 12V
of
the
T/R
circuit
board,
to
switch SW2
lug2(S-2).
(
)
Connect
the
free
end
of the
brown
wire, com-
ing
from
hole
+T of
the T/R
circuit
board, to
control
R2 lug 3
(NS).
Route
this
wire
as
shown
in the
Pictorial.
Refer to
Pictorial
3-8 (Illustration
Booklet,
Page
25)
for the
following
steps.
(
)
Route
the
8-wire cable
coming
from the
T/R
circuit
board
around
the
VFO
assembly,
along
the
front
of the
chassis,
and
down the
corner
to
the
other
side
of the
chassis
as
shown
in
the
Pictorial.
Connect
some
of
the
wires
coming
from the
free
end
of
the
8-wire
cable as
follows:
(
)
Violet
wire
to
control
Rl lug 1
(NS).
(
)
Gray
wire to
control
Rl
lug
3
(S-l).
(
)
Red
wire to
control
R2 lug 2
(NS).
(
)
Brown
wire to
control R2
lug
3
(NS).
(
)
Prepare the
following
wires:
three
1"
small
bare
one
8"
large
red
stranded
(
)
Connect a
1"
bare
wire
from control
R3
lug
3 (NS) to
the
nearby
solder
lug
(S-l).
(
)
Connect
a
1"
bare
wire between
control Rl lugs
1
(S-2)
and 2 (S-l).
(
)
Connect a
1"
bare
wire from
control R2
lug
1 (NS)
to the
nearby solder lug
(S-l).
(
)
Connect
one end of the
8"
large
red wire to
switch
SW2 lug 1
(S-l). The
other end of
this
wire will be
connected
later.
(
)
C3:
Cut both
leads of a
.01 [xF
(103)
glass ce-
ramic capacitor
to
1/2".
Then connect
the
capacitor
between
control R2 lugs 1
(NS) and
2 (S-2).
(
)
C4:
Cut
both leads
of
a
.01
(103)
glass ce-
ramic
capacitor to
5/8".
Then connect
the
capacitor
between control
R2 lugs 1
(NS) to
3
(NS).
(
)
R5: Cut
both leads
of a 1000
il
(brn-blk-red)
resistor to
1/2".
Then
connect the
resistor be-
tween
control R2
lugs 1
(S-4)
and 3 (S-4).
(
)
Route
the
brown-red
2-wire cable across
the
circuit board
and out
through the large
rectan-
gular
hole in the
front of the
chassis as shown
in the
Pictorial. The
free ends
of these wires
will be connected
later.
(
)
Connect
the free
end of the
shielded cable,
coming from
holes
Audio/In and
GND on the
T/R
circuit board, to
control R3 as
follows:
4
Inner lead to lug
2 (S-l).
Shield wires to
lug 3 (NS).
( )
Prepare
an
8"
shielded
cable.
Then connect
the
wires at one
end of the
cable to
control R3
as
follows:
Inner lead to lug
1 (S-l).
Shield
wire
to
lug 3 (S-3).
(
)
Route the
free end of the
cable
coming from
control R3 as
shown in the
Pictorial; it
will
be
connected later.
