NOTES ON ASSEMBLY
Try
to
provide
a
work area that will
not have
to be cleared or
disturbed if
your
work
should be
i.nterrupted. It is much easier to
resume construction
if
everything can
remain in its
place
until
completion of the
kit. Provide
yourself
with
good
quality
tools as the
use
of
improper or inferior
tools will cause
your
workmanship
to
suffer and
result in
longer
assembly time. There
is
afso
a
great
deal ofpersonal satisfaction
in
a
neat
professional
looking
adapter,
resultingfrom care-
ful assembly and
wiring.
Basic tool
requirements
consist of a
screwdriver
with a 1/4"
blade;
a
small screwdriver
with a 1/8"
blade for
setscrews and adjustments; long
nose
pliers
used
to
form leads and hold
parts;
wire
cutters,
preferably
separate diagonal
cutters; a
penknife,
or
preferably
a tool for
stripping insulation
from wiresl a
soldering iron
or
gun
and rosin
core
radio solder, Be
sure to
read the
paragraphs
on
soldering
before
you
start. wiring the adapter.
UNPACK
THE KIT
CAREFULLY
AND
CHECK
EACH PART AGAINST THE PARTS
LIST. IN
so
doing,
you
will become acquainted
with each
part.
Refer to the charts and other
inlormation
shown
on the inside covers ofthe
Manual to
help
you
identify
any
parts
aboutwhich there
may be
a
question.
If
some
shortage is found
in
checking
theparts,
please
notifyus
promptly
and
return
the
inspection slip
with
your
letter to
us. Hardware
items
are
countedby
weight
and iJ a
few
are
missing,
please
obtain them
locally
if at all
possible
to avoid
delay in
the construction
of
your
kit.
Resistors
and
controls
generally
have a
tolerance
rating
of. t20Vo unless otherwise stated
in the
Parts List, therefore, a 1
K!) resistor may
test anywhere from
800Q
to
12004
(the
letter
K is
commonly
used to designate a multiplier
of
1000). Tolerances on capacitors are
generally
even
greater.
Limits of
+100%
and
-5.07o
are common
for electrolytic capacitors. The
parts
fur-
nished with
your
Heathkit have been
specified
so as to not adversely affect the operation
of the
finished instrument.
In order
to expedite
delivery to
you,
we
are occasionally
forced to make minor substitutions
of
parts.
Such substitutions are carefully
checked
before they are approved and the
parts
supplied
wiII work
satisfactorily. By checking the
Parts List for resistors, for example,
you
may
find
tbat a 1200O resistor has been
supplied
in
place
of a 1
KQ
as
shown in
the
Parts List. These
changes
are
self
evident andare
mentionedhere
only
to
prevent
con-tusion
in eheckingthe
contents
of
vour
kit.
Most kit
builders find it helpful
to
separate
the
various
parts
into
convenient
categories.
Muff
in
tins
or molded
egg
cartons
make
convenient
trays
for
small
parts.
Resistors
and
capac-
itors
may be
placed
in
the edge
of a
piece
of
corrugated cardboard
until
they
are
needed.
Values can be written on the cardboard
next to
each
component. The
illustration
shows
one
method
that may be
used. Read through
the
en-
tire
Manual
before
starting construction.
In
this
way
you
will become
familiar
with
the
tech-
niques
employed
inbuildingthe
kit.
As
a further
deterrent
to errors,
read
each
step of the
con-
struction
and wiring completely
before
perform-
ing
that step.
Do
not
try
to hurry
your
work
or to
work
for too
long a
period
atone
time.
Bothcourseswilllead
to carelessness and increased
possibility
oferror.
The instructions
and
illustrations have been
prepared
to assist
you
in every
detail during construction and use of
your
adapter. We urge
you
to follow them carefully and thus avoid
improper
operation or the
possibility
of
damage to
components through errors
in
construction.
There is
a
great
satisfaction in having
your
adapter
work
properly
the first time
you
turn
it on
- -
do not deny
yourself
this
pleasure
through careless
work.
