Step-By-Step Assembly - Heathkit SW-717 Assembly

STEP.BY-STEP ASSEMBLY
Before
starting
to
assemble
this
kit,
read
the
"Kit
Builders
Guide"
for
complete information on wiring,
soldering,
and
step-by-step assembly
procedu
res.
Use
1/2-watt
resistors unless
directed
otherwise
in
a
step.
Resistors are designated
by the color code and the
resistance
value.
The
symbol
fl
means
ohms, and
K or kQ
indicates
1,000 ohms.
Capacitors are designated
by their
value
and
type. The symbol
pF
means
microfarad, and
pF
means
picofarad.
1
pF
is
equal
to
1,000,0O0 pF.
Before
you
install
a disc
capacitor, remove
from its
leads any
excess
body coating material which would
protrude through
the
circuit board and prevent soldering the
leads
to
the
foil.
Be
very
careful
not
to
cover unused holes
with
solder or
bridge
solder between
foils
during
the
assembly
of
the
circuit
board. Use a
soldering
iron that
is rated
at
15
to
25
watts.
lts
tip
should be
no
wrder
tnan
1/1
6"
at its
widest
dimension; a pyramid or
chisel-shaped
tip
is best. This
type
of
soldering iron
will
make
the
kit
easier
to
assemble,
with
less
chance
of
solder
bridges
occurring. Solder
a part, or
group of parts, only
when
instructed
to
do
so.
