REPLACEABLE PARTS
6-1. INTRODUCTION
6-2. This section contains information for ordering carts. Table
6-1 lists the available exchange assemblies. Table 6-2 lists
abbreviations used in the parts lists and the names and addresses
that correspond with the manufacturers' code numbers. Tables 6-3A
and 6-3B list the replaceable parts in reference designator order
for the 85020A and 85020B separately. Only the listed parts are
replaceable.
6-3. EXCHANGE ASSEMBLIES
6-4. The microcircuit bridge assembly, including incut and test
port connectors and the reference termination, may be replaced on
an exchange basis, thus affording a considerable cost savings.
Table 6-1 lists these assemblies for both Directional Bridges,
together with the part numbers for the exchange assemblies.
Exchange, factory repaired and tested assemblies are available
only on a trade-in basis? therefore, the defective assemblies must
be returned for credit. For this reason, assemblies required for
spare parts stock must be ordered by the new assembly part number.
