The circuit component's number appears on the diagrams
and circuit board illustrations. Each diagram and circuit
board illustration is clearly marked with the assembly
number. Assembly numbers are also marked on the me­
chanical exploded views located in the mechanical parts list.
The component number is obtained by adding the assembly
number prefix to the circuit number.
The electrical parts list is divided and arranged by assem­
blies in numerical sequence (e.g., assembly A1 with its
subassemblies and parts, precedes assembly A2 with its
subassemblies and parts).
Chassis-mounted parts have no assembly number prefix
and are located at the end of the electrical parts list.

ment part from Tektronix.

NAME & DESCRIPTION
(column five of the parts list)
In the parts list, an item name is separated from the descrip­
tion by a colon (:). Because of space limitations, an item
name may sometimes appear as incomplete. For further

H6-1 can be utilized where possible.
