Solder the 1/2 inch spring to the PC board as shown in Figure 4-3. This
spring will contact the metal shield on the case bottom when the bottom
is installed.

Insert the narrow end of the three input sockets into the PC board from the component side, as shown in
Figure 4-4. Solder the sockets to the PC board on the components side only. The solder should extend
completely around the socket (see Figure 4-4).
Insert the shunt wire (R0) into the PC board holes from the component side as shown in Figure 4-4. Adjust
the wire so that it sticks out the other (solder) side of the PC board 3/16 of an inch. Solder the wire to the
PC board on the component side only.
Be sure that the 8 pin transistor socket will slide easily through its hole in the top case from either direction.
If it does not, carefully slide it through the hole several times in each direction to remove any burrs. Do not
push on the socket leads or they may be damaged.
Insert the socket into the PC board holes from the solder side as shown in Figure 4-4. Be sure that the tab
lines up with the hole as shown in the figure. Solder the socket to the PC board on the component side of
the PC board as shown in the figure and cut off excess leads.
Feed the battery snap wires up through the hole in the PC board from the solder side as shown in Figure 4-4.
Insert the red wire into the hole marked (V+) and black wire into hole marked (V--) as shown. Solder the wires
to the PC board.
Insert the two fuse clips into the PC board holes as shown in Figure 4-4. Be sure that the tabs are on the
outside as shown in the figure. Solder the clips to the PC board.
Install the following parts. Then, place a check mark in the box provided.
