WJ-8718-19/FE HF RECEIVER REPLACEMENT PARTS LIST
5.4 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 semiconductors become avail
able, it is the policy of Watkins-Johnson
to incorporate them in proprietary
products. For this reason some
transistors, diodes, and integrated circuits
installed in the equipment may not agree
with those specified in the parts list and
schematic diagrams of this manual.
However, the semiconductors designated in
the manual may be substituted in every
case with satisfactory results.
