PARTS
Resistors are identified in Parts Lists and steps by
their resistance value in ft (ohms), kft (kilohms), or
Mft (megohms). They are usually identified by a color
code and four or five color bands, where each color
represents a number. These colors (except for the last
band, which indicates a resistor's "tolerance") will be
given in the steps in their proper order. Therefore, the
following color code is given for information only.
NOTE: Occasionally, a "precision" or "power" resis
tor may have the value stamped on it.

Capacitors will be called out by their capacitance
value in /xF (microfarads) or pF (picofarads) and type:
ceramic, Mylar*, electrolytic, etc. Some capacitors
may have their value printed in the following man
ner:
First digit of
capacitor's value: 1 ■
Second digit of
capacitor's value: 5 -
Multiplier: Multiply the
first & second digits by
the proper value from the
Multiplier Chart.
To find the tolerance of
the capacitor, look up
this letter in the Tolerance
columns.

EXAMPLES:
151K = 15 x 10 = 150 pF
759 = 75 X0.1 = 7.5 pF
NOTE: The letter "R" may be used at times to signify a
decimal point: as in: 2R2 = 2.2 (pF or /xF).
