Q. I don't have a 12-volt DC power supply for those Progress
Tests outlined in this manual. The cheapest one at Radio Shack™
is $30 what do I do?
up to a car battery, but we'll assume you wish to provide the 8
"C" cells accommodated by your receiver's go-anywhere design:
if so, the battery holder/shelf/snap connector assembly detailed
in Steps 7-2 ff. will provide 12VDC as needed for this project.
Q. What is the most important single procedure in the whole
building process?
by step, for correct parts selection and orientation.
Q. Which kit-builders tend to make the most mistakes?
A. Typically, professional technicians and experienced do-it-
your-selfers, who ARE very good with electronics, may not have
the patience to follow the steady pace of complete part-by-part
directions. What to do seems so obvious to them that they
"stuff the board" very quickly, and then they need to spend lots
more time tracing just one or two little but critical mistakes. This
is common in most hobbies and crafts.
Before Soldering ANY Parts:
You will want to do some kind of sorting and grouping of the kit
parts to make them easier to find. ln particular, be sure to
separate the 9 molded inductors from the 21 1/4-watt resistors.
The inductors have a blue-green background and are slightly
fatter and shorter than the resistors. They also have a very low
resistance (one ohm or less) if measured with your ohmmeter.
Our 1/4-watt resistors normally have a tan background color,
though NOT always! The main possibility for confusion occurs
with R18 and R23, both 3.3 ohms, and L6, 3.3 microhenries, all
with the same color code of orange-orange-gold-gold! R18 and
R23 are installed early in Phase 1.0; simply keep L6 with the
other inductors until they are installed all together.
