r
Insert the narrow end of the three input sockets
into the PC board from the top legend, as shown in
Figure E. Solder the sockets to the PC board on
the component side only. The solder should extend
completely around the socket (see Figure E).
r
Insert the shunt wire (R9) into the PC board holes
from the component side as shown in Figure E. Adjust
the wire so that it sticks out the other (solder) side of
the PC board 1/8”. Solder the wire to the PC board on
the component side only. Cut excess leads flush.
r
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.
r
Insert the socket into the PC board holes from the
solder side as shown in Figure E. 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.
r
Feed the battery snap wires up through the holes
in the PC board from the solder side as shown in
Figure E. Insert the red wire into the hole marked
(9V+) and black wire into hole marked (9V–) as
shown. Solder the wires to the PC board.
r
Insert the two fuse clips into the PC board holes
on the component side as shown in Figure E. Be
sure that the tabs are on the outside as shown in
the figure. Solder the clips to the PC board.
