ASSEMBLY
(
)
Refer
to
Pictorial
2-1 (Illustration
Booklet,
Page

for
the
following
steps.
(
)
Position
the
T/R circuit
board as
shown in the
Pictorial.
NOTE:
Due
to the
density of
this circuit
board,
You
will
first
install the
taped
components
that
mount
horizontally
on the
circuit
board.
When
you have
these
installed, you
will
install the
taped
compo-
nents
that
mount
vertically.
Install a
component
in Section
1 of the
circuit
board
as
follows:
(
)
D406:
1N4149
diode
(#56-56).
Be
sure to
posi-
tion the
banded end as
shown
on the
circuit
board.
(
)
Solder the
leads to
the foil
and cut
off the ex-
cess
lead
lengths.
Install
components
in Section
2 of
the circuit
board
as
follows:
(
)
C446:
.1
(104)
glass
ceramic capacitor.
(
)
D405:1N4753A
diode (#56-55).
(
)
C424:
.01
\lF
(103)
glass
ceramic
capacitor.
(
)
D401:1N4149
diode
(#56-56).
(
)
Solder the
leads to
the
foil and cut
off the
ex-
cess lead
lengths.
Install
components in
Section 3
of the circuit
board
as
follows:
(
)
R3
34: 1 000 ft
(brn-blk-red)
resistor.
(
)
R428:
680 ft
(blu-gry-brn)
