Components assigned anasterisk (*) are factory
selected, average values shown.
(9. 4. 7) indicates wire color code. Wire color
code (MIL-STD-681) same as resistor
color
code. First number identifies ground color,
second number identifies wide stripe,
third
number identifies narrow stripe, i. e. (9. 4. 7)
denotes white ground, yellowwide stripe, violet
narrow stripe.
The components mounted on chassis or main-
frame parts are not assigned anassemblydesig-
nation (i.e. Rl, Ql, etc. ).
Reference designations (Rl, Ql, etc. ) within
assembly (Al, A2. . . . etc. ) use assembly desig-
nation as prefix to form complete designation.
(i. e. Rl in Al assembly is AlRl)
Additional notes are shown in Figure 8-l.
