Connect
one nd of the 6S00-ohm
(bi
ue. gray,
red).
1-watt resistor to lug
;;2
(square
symbol)
of
the
filter capacitor.
Connect
the
other
end
to lug
#3
(triangle
symbol)
of
the
capacitor.
The
resistor leads
should
be
cut
to
permit
mounting
exactly
as
is shown
in
the
diagram.
27( )
Connect
one
end
of the 50-ohm,
5-watt
resistor to
lug

(curved
line
symbol)
of
the
filter capacitor.
Connect
the
other
end
to lug
:#I

(square
symbol)
of the
capacitor
(S).
Check to be
sure
that
all
four
of the connections
at
lug
#2
have been
solden~d,
and
that
excess wire has been
trimmed
away,
and
cannot
touch
the chassis
or
adjacent
lugs.
2S( )
Connect
one
end
of the 95-ohm,
5-watt
resistor to lug

The
silicon rectifier diodes
supplied
with the
kit
may
be
of
any
of the
three
types shown in
the
illustration;
although
differing in
external
appearance,
the
three
types
are
electrically
equivalent.
Connect
the
CATHODE
lead of one
of
the
rectifier diodes to lug # 1
(curved
line
symbol)
of
the
filter
capacitor.
Connect
the
ANODE
lead
to lug
-#
2 of
the
5-lug
terminal
strip
r
8).
IMPORTANT:
Arrange
the
-·E--
diode leads
exactly
as
shown
in
the
pictorial
diagram.
When
soldering,
hold a pliers
on
the
lead
between
the
diode
body
and
the
solder
connection
to avoid
application
of excessive
heat
to the diode.
31 ( )
Connect
the
CATHODE
lead of
the
other
rectifier
diode
to lug # 1
(curved

Connect
the
other
lead to
lug
# 1 of
the
5-lug terminal
strip
(8).
Observe
the
same
pre-
cautions
when
soldering
as
in
the
preceding
step.
32 ( )
Connect
one
end
of a
4"
wire to lug C of
the
RIGHT

chassis-mounting
lug A of
the
filter
capacitor.
33(

.
34 ( )
Connect
one
end
of a 4" wire to
lug
# 3
(triangle
symbol)
of the filter
capacitor.
Connect
the
other
end
to
eyelet
#7
of the
RIGHT
circuit
board
(8).
NOTE:
Before
making
a
connection
to
an
eye-
let
on
the
circuit
board,
tin
the
end
of
the
wire
by
heating
it
with
the
soldering
iron
and
touch-
ing
solder
to it.
The
wire
end
is
tinned
when
the
solder
melts
and
runs
onto
the wire.
The
eyelets
on
the
board
already
have
solder
in
them.
To
solder
to
the
eyelet,
heat
it
with
the
soldering iron
and
insert
the
end
of the wire
when
the
solder
in
the
eyelet
flows.
Remove
the
iron
and
hold
the
wire in
place
until
the
solder
hardens.
