PARTS REPLACEMENT

Replacing

The exploded view drawings associated with the

Mechanical Parts Lists, located to the rear of most
manuals, may be especially helpful when disassembling
or reassembling individual components or sub-
assemblies.

Circuit Boards. If a circuit board is damaged

beyond repair, the entire assembly including all
soldered-on components, can be replaced. Part
numbers are given in the mechanical parts lists for the
completely wired (670 prefix) board.

To remove or replace a board, proceed as follows:

1. Disconnect all leads connected to the board

(both soldered lead connections and solderless pin
connections).

2. Remove all screws holding the board to the

chassis or other mounting surface. Some boards may be
held fast by plastic mounting clips around the board

edges. For these, push the mounting clips away from
the circuit board edges to free the board. Also, remove
any knobs, etc., that would prevent the board from being
lifted out of the instrument.

3. Lift the circuit board out of the unit. Do not force

or bend the board.

4. To replace the board, reverse the order of

removal. Use care when replacing pin connectors; if
forced into place incorrectly positioned, the pin
connectors may be damaged.

Transistors and IC's. Transistors and IC's should

not be replaced unless they are actually defective. If
removed from their sockets during routine maintenance
return them to their original sockets. Unnecessary
replacement or switching of semiconductor devices
may affect the calibration of the instruments. When a
transistor is replaced, check the operation of the part of
the instrument that may be affected.
