CONSTRUCTION NOTES
This manual is supplied to assist you in every
way to complete your kit with the least possible
chance for error. The arrangement shown
is
the result of extensive experimentation and
trial.
If followed carefully, the result will be a
stable instrument, operating at a high degree
of dependability. We suggest that you retain the
manual in your files for future reference, both
in the use of the instrument and for its main-
tenance.
UNPACK THE KIT CAREFULLY
AND CHECK
EACH PART AGAINST THE PARTS LIST. In so
doing, you will become acquaintedwiththeparts.
Refer to the charts and other information onthe
inside covers of the manual to help you identify
the components.
If some shortage or parts
damage is found in checking the Parts List,
please read the REPLACEMENT section and
supply the information calledfortherein. Include
all inspection slips in your letter
to us.
Resistors generally have a tolerance rating of
10%unless otherwise stated in the Parts List.
Tolerances on capacitors are generally even
greater. Limits of
+ 1000/0and -20 O/o are common
for electrolytic capacitors.
We suggestthat you do the following before work
is started:
1. Lay out all parts so that they are readily
available.
2. Provide yourself with good quality tools.
Basictool requirements consist of a screw-
driver with a
1/4" blade; a small screw-
driver with a
1/8" blade; long-nose pliers;
wire cutters, preferably separate diagonal
cutters; a pen knife or a tool for stripping
insulation from wires; a soldering iron (or
gun) and rosin core solder. A set of nut
drivers and a nut starter, while not neces-
sary, willaid extensively in construction of
the kit.
Most kit builders find it helpful to separate the
various parts into convenient categories. Muffin
tins or molded egg cartons make convenient
trays for small parts. Resistors and capaci-
tors may be placed with their lead ends in-
serted 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.

PROPER SOLDERING TECHNIQUES
Only a small percentage of HEATHKIT equip-
ment purchasers find it necessary to return
an
instrument for factory service. Of theseinstru-
ments, by far the largest portion
malfunction
due to poor or improper soldering.
If terminals are brightandclean andfreeof wax,
frayed insulation and other foreign substances,
no difficulty will be experienced in soldering.
Correctly soldered connections are essential
if
the performance engineered intc; a kit is to be
fully realized.
If you are a beginner with no
experience in soldering, a half hour's practice
with some odd lengths of wire may be a worth-
while investment.
For most wiring, a 30 to 100 watt iron or its
equivalent in asoldering
gun isvery satisfactory.
A lower wattage iron than this may not heat the
connection enough to flow the solder smoothly
over the joint. Keep the iron tipclean and bright
by wiping it from time to time with a cloth.
Wherever there isapossibilityof bare leads
shorting to other parts orto the chassis,the
leads should be covered with insulating
sleeving. Where the use of sleeving is spe-
cifically intended, thephrase "use sleeving"
is included in the associated construction
step.
In any case where there is the pos-
sibility of an unintentional short circuit,
sleeving should be used, Extra sleeving is
provided for this purpose.
4.
Crimp or bend the lead (orleads)aroundthe
terminal to form a good joint without re-
lying on solder for physical strength.
If
the wire is too large to allow bending or if
the step states that the wire is not to be
crimped, position the wire so that a good
solder connection can still be made.
5.
Position the work, if possible, sothat gravity
will help to keep the solder where you want
it.
