Cut two
3/8"
lengths
of
insulation
from the
yellow
length laid
aside earlier.
Place
one
3/8"
length
on
each
lead
of
the other
transistor. Position
the
transistor
with
the
flat
side
away
from
the
chassis.
Connect
the
base lead
to
lug
3
(S-2)
and
the emitter
lead
to
lug
5
(NS)
of terminal
strip
BF.
( )
Connect
the
banded
end
of
the
zener
diode
(#56-1g)
to
lug
2
(NS) and
the other
end
to
lug
4
(NS)
of
terminal
strip
BF.
NOTE:
When
you
connect
a
wireto
the
circuit
board
in
the
foflowing
steps,
do not
insert
more
than
118"
of
the
wire
into the
circuit
board hole.
( )
Connect
a
17-1
12"
length
of
green
hookup
wire from
lug
3
of
phone
jack E
(S-1
)
to
hole
B
on the circuit
board
(S-1
).
Route
the wire
as
shown
in
Pictorial
14.
Refer
to
Pictorial
15
(fold-out
from
Page
31)
for
the
following
steps.
NOTE:
To
"prepare"
a
hookup wire.
cut
it
to
length
and
then
remove 114"
of
insulation
from mch
end.
Be careful
not
to
nick the wire
when
you cut the insulation.

Prepare
the
following
lengths
of
blue
hookup wire:
1-114"
1-1/2"
2"

blue
hookup wire
from
lug 5
of terminal
strip BF
(S-3)
to
hole
HH on
the
circuit
board
(S-1).

Connect
a
4-112"
blue
hookup
wire from
lug
2

( )
Cut
each
lead
of
the 500 pF electrolytic capacitor
to
a
length
of
3/4".
( )
Connect
the
lead at
the positive
(+) end
of
the
500 pF
electrolytic
capacitor
to
lug 2
(S-4)
and
the other
lead
to
lug
6

of terminal
strip
BF.
Make sure
the
body
of
this
capacitor
does
not touch the
leads
of
any
component mounted
on the
terminal strip.

Connect
the 390
Q
(orange-white-brown) resistor
from
lug
1
(NS)

yellow
wire
coming
from
lug
5
of
terminal strip
AL
to
lug
1
of
