RCA 54-45 Manual page 6

Components such as RESISTORS and CAPACITORS, may have longer leads than specified. Cut
the leads to the length indicated in the particular construction step. This length is to be measured
from the body of the component. In the case of insulated leads, strip 1/4" of insulation off from the
ends and twist the strands (if any) of the wire together.
AS AN EXAMPLE, one step may specify that each lead on a resistor be cut to 1/2". 1/4" of
each lead is used to make a mechanical connection to the solder lug. The other 1/4" is between the
terminal board and the component so that the component will not be overheated when soldering.
When a CONNECTION
indicates that the connection should be simply mechanical. WITHOUT SOLDERING, since other
leads are to be connected to this same lug. The (S) indicates that the connection should be made and
soldered immediately. However, the (S) is always followed by a number, such as (S1), (S2), (S3),
etc. This number indicates the NUMBER OF CONNECTIONS made and soldered to the lug. It is a
check on the accuracy of your work.
AS AN EXAMPLE, if it says (8a) you should count three leads going to the lug to be soldered.
If there are less than three leads at this particular lug, you will know that you have forgotten one or
more leads, or connected them to the wrong lugs. If there are more than three leads, you can be
certain you have connected an extra wire to this lug, which should probably
WHEN YOU ASSEMBLE the parts in your unit, mark the symbol of each component on the
chassis near the part, with a c:uayon. This will facilitate your wiring operation.
WHEN WIRING, lay the component in close to the chassis and dress it as shown in the drawing.
BE CAREFUL to avoid shorts at the lugs. The book is written so that the wiring closest to the
chassis usually gets wired in first. The next layer of wires are to be soldered in next.
dress the leads and components as close to the chassis as possible.
NOTE: Although the pictorials are correct insofar as the connections made, they
NOT in any way reflect the ACTUAL LENGTHS or PLACEMENT OF LEADS.
We may, in some cases, distort the actual component or lead placement to
provide the kit building with a clearer illustration. Nevertheless, the wires
and component leads must be cut according to the WRITTEN INSTRUCTIONS.
STEPS
THE
Next to each step you will find a number enclosed by a circle. This circled number corres­
ponds directly to the dark circle number on the figures. These numbers refer to the particular step
that the component is mounted or wired.
After you have completed each step, make a check mark or cross out the number next to the
step so that you will have a complete record of your work.
Follow the-steps in the sequence given in the book.

NOTE: One of the most common errors that people make occurs when a step is not
completely read BEFORE attempting any work on it. Please read the
ENTIRE step first.
Once more, if any addenda sheets have been included in your books to modernize your kit or to
make corrections or part substitutions, be sure to make these corrections first, before you start to
assembly your kit.
