Bill of Materials Introduction
General
Band-Specific Components
The components marked "band-specific" have values that are determined by the particular band for which the rig was kitted. See the Sub-bill (links are listed below the detailed Bill of Materials herein) that corresoponds to your kit's band.
Orientation
Resistors
Resistors can be oriented in "hairpin" style, with the body of the resistor snugged vertically in the hole with the silk-screened circle and the "hairpin" lead into the resistor's other hole (pointed to by the tiny silk-screened tickmark). Hairpin orientations can be N-S, S-N, E-W, or W-E. For example a hairpin-mounted resistor with N-S orientation would have the body in the "northern" hole and the hairpin lead in the "southern hole".
Resistors can also be oriented as "flat-h" and "flat-v", indicating a flat-mounted resistor in, respectively, a horizintal orientation or a vertical orientation.
ICs
Orientation of ICs may be illustrated via images of the IC to indicate how the chip is oriented with respect to its pin 1. On Tony's board, the pin 1 location is indicated by a "1" (which, depending upon how you view it, may resemble a zero).
