Finding the right part:
IC's
The outline on the board for the IC's has a "U" notch on one end, indicating pin 1 end of the IC. There is
also a notch on one end of the sockets. This end goes over the "U" notch outline on the board. Finally,
pin 1 of the IC is marked with a round dimple or dot; this end of IC will go towards the notch on the
socket or "U" on the outline.
Diodes
Be sure to observe proper polarity of diodes. There is a black band towards one end of the diode. This
band should face the line shown on the diode outline of the board.
Electrolytic capacitors:
These must be installed with the correct polarity. The positive (+) lead is always the long lead. The
negative (-) lead is marked by a stripe on the body of the capacitor can. Make sure the plus end of the
cap goes toward the hole labeled with the (+).
Coils and Transformers:
You can find it convenient to wind and prepare all the coils and transformers before you start inserting
parts. That way you don't need to stop and possibly loose concentration to wind them.
Is the part of the build considered by some to be the most difficult. I find it one of the easiest stages,
personally, and almost relaxing. Just take your time. The assembly instructions and pictures illustrate the
process.
