PARTS LIST
The parts list which follows contains all electrical parts used in the equipment and
certain mechanical parts Which are subject to unusual wear or damage.
When ordering
replacement parts from Watkins-Johnson Company, specify the type and serial number of the
equipment and the reference designation and description of each part ordered.
The list of
manufacturers provided in paragraph 5.3 and the manufacturer's part number for components
are included as a guide to the user of the equipment in the field.
These parts may not
necessarily agree with the parts installed in the equipment; however, the parts specified in this
list will provide satisfactory operation of the equipment. Replacement parts may be obtained
from any manufacturer as long as the physical and electrical parameters of the part selected
agree with the original indicated part.
In the case of components defined by a military or
industrial specification, a vendor which can provide the necessary component is suggested as a
convenience to the user.
NOTE
As improved semi-conductors become avail-
able, it is the policy of Watkins-Johnson to
incorporate them in proprietary products. For
this reason some transistors, diodes, and inte-
grated circuits installed in the equipment may
not agree with those specified in the parts list
and
schematic
diagrams
of
this
manual.
However, the semi-conductors designated in
the manual may be substituted in every case
with satisfactory results.

ASSEMBLY REVISION LEVEL
The purpose of the Assembly Revision Level is to identify the "as built" configuration
of an assembly or subassembly. The parts list and illustrations that follow, depict the revision
levels of the assemblies and subassemblies at the time of preparation of the manual, which may
or may not agree with the purchased equipment. However, they will serve as a guide for any
necessary maintenance to be performed.
Refer to Table 5-1 for the equipment assembly
revision level record(s).
