Replacement. (figures 2-11 and 2-12). Most of the chassis components in the AN/G RA-39(*) are removed by

unscrewing attaching hardware and/or unsoldering wires. The components are easily reached with the chassis

removed from the case.

CAUTION

Do not use a soldering gun; damaging voltages can be induced in components. Use a

pencil-type soldering iron with a 25-watt maximum capacity. Both control units are

transistorized. If only at-operated irons are available, use an isolating transformer.

NOTE

When removing soldered leads, tag each lead as it is unsoldered from its terminal.

(1) Release clamp on each side of control unit and slide chassis out of case.

(2) Unsolder wire(s) from component.

(3) Remove attaching hardware, if applicable, and remove component from chassis.

(4) Position replacement component on chassis. Secured with attaching hardware, if applicable.

(5) Solder tagged wire(s) to proper component terminal(s).

(6) Slide control unit into case and secure with clamps.
