connect the 1-1
12"
hookup wire from lug 4
(S-1)
to
(
)
Prepare
the following
lengths
of
yellow
hookup
wire:
hole O on
the
circuit
board
(S-1).
(

(S-1).
(
)
Connect the
4" hookup wire from lug
8
(S-1)
to hole
R on the circuit
board
(S-1
).
(
)
Connect the hookup wire
coming from
hole
X on
the
circuit board to
lug
21
(NS).
(
)
Connect the7"
hookup wire from
lug
21
(S-2)
to the
terminal lug
on
variable capacitor G
(S-1),
(
)
Inspect the connections at
lug
21
carefully
to
make
sure
there is NO contact between
them and
the three
adjacent
solder
lugs.
(
)
Connect the
hookup wire coming
from
lug
12
of water
#2
of switch C
to hole
M
on
the circuit board
(S-1).
The letter M may be
partially
obscured by
the edge of
the
chassis.
Refer
to
Pictorial
21
for the following steps.
)
Bend
the solder
lug at BS and
lug
1 of
control A so
they touch
each other.
lt
may be
necessary
to
reposition the control.

Connect a 20
pF
disc
capacitor
from lug
2
(NS)
to lug
1
(NS)
of control
A.

the
circuit board
(S-1).
{ }
Connect one end
of a 2"
yellow
hookup
wire
to
hole
X on the circuit
board
(S-1).
Position
the wire
between
the switch
and the chassis. The free end
will
be connected
later,
Wire
the lugs
on the
front
of wafer
#2
