Thread
the
twisted
pair
of
red wires from

the
board,
connect
these wires
to
lugs
#2
and
#3
of
the
transformer
T73,
as indi-
cated
in
the
diagram.
Wrap
each
wire
around
the
lug
and
solder
it
to
the
lug
and
to
the
copper
on
the
board.
Note
that
this
transformer
has
5
connecting
lugs
positioned
around
the
access hole.
Be
sure
that
the
red
wires
are
soldered
to
the
proper
points.
Either
wire
may
connect
to
either
lug.
Be
sure
that
bare
wire
does
not
contact
adjacent
circuit
points.

Mount
the
discriminator
transformer
T5
(432002).
This
transfornH'r has five
connecting
lugs
and
two
mounting
tabs,
It
can
be mount(,d in only
one
po-
sition.
Press
it
firmly to
the
board
and
solder
both
mounting
tabs
and
the
five connl:cting lugs. Do
not
use
excessivp
heat
on
the
five lugs. Avoid
using
too
much
solder, which
could
flow into
the
transformer
and
damage
it.

Insert
the
end
of
the
line
cord
through
grommet
#3
in
the
rear

the
chassis
and
pull
through
about
6
inches.
Tie
a Imot 4
inches
from
the
end,
and
pull
the
line
cord
back
so
that
the
knot
seats
against
the
grommet.
Split
the
two
conductors
of
the
line
cord
down
to
the
knot.
Connect
one
of
the
two
leads
to
lug
# 1 of
the
fuse
holder
(S-2).
Connect
the
other
lead
to
lug
#5
of
the
five
lug
terminal
strip
(S-2).
Now
check
to
see
that
the
black
twisted
pair,
of
which
one
wire
connects
to
lug
#5,
is
positioned
away
from PC-12.
