STEP-BY-STEP ASSEMBLY
IMPORTANT:
Before you start to assemble this kit, read the wiring
and soldering information in the “Kit Builders Guide.”
Due to the smal! foil area around the circuit board
holes and the small areas between foils, it will be
necessary to use the utmost care to prevent solder
bridges between adjacent foil areas. Use only a
minimum amount of solder and use no larger than a
40-watt soldering iron with a small tip. Allow it to
reach operating temperature and then apply it only
long enough to make a good solder connection.
Resistors will be called out by their resistance value in
Q, kQ or MQ, and by their first three color bands. The
Capacitors will be called out by their capacitance value
(in PF or pF) and type (ceramic, tantalum, or
electrolytic).
A separate ‘‘Illustration Booklet” contains numbered
istustrations (Pictorials, Details, etc.) that are too large
for the Assembly Manual. The Step-by-Step Assembly
instructions will direct you to the proper illustration
in the Booklet. After you have completed the
assembly of your kit, place the Hlustration Booklet
with the Assembly Manual and save them for future
reference.
fourth color band is normally gold, which indicates a [SAFETY WARNING: Avoid eye injury when you clip off
5% tolerance. However, when a tolerance of 10% is excess lead lengths. We suggest that you hold the leads, or at
given ina step, the fourth color band will be silver. least clip the leads so the ends will not fly toward your eyes.
