2-10. RF Filter Assembly (A-, B- and C- Models Only)
This task covers: Replacement
Tool Kit, Electronic Equipment TK-105/G
Do not use a soldering gun. Damaging voltages can be induced in the components. Use
transistorized. If only an at-operated iron is available, use an isolating transformer.
When removing soldered leads, tag each lead for identification as it is unsoldered from its
terminal to facilitate reconnection.
The specific components that comprise the RF filter assembly vary depending on the
particular control unit (local or remote) and model. The procedures described in this
paragraph are typical for all units and models.
The C-2328A/GRA-39 and C-2329A/GRA-39 (comprising the AN/GRA-39A) have sealed
RF filter assemblies consisting of unspecified components that cannot be replaced
individually. if a fault is detected, the entire sealed unit must be replaced.
(1) Release clamp on each side of control unit and slide chassis out of case.
(2) Tag and unsolder wires connected to RF filter assembly components (1) and remove components from
(3) Position new RF filter assembly components (1) on chassis (2) and solder tagged wires to proper
terminals on RF components.
(4) Slide chassis into case and secure with clamps.
