r Insert the narrow end of the three input sockets
into the PC board from the top legend, as shown
in Figure F. Solder the sockets to the PC board on
the top legend only. The solder should extend
completely around the socket (see Figure F).
r Insert the shunt wire (R13) into the PC board
holes from the component side as shown in
Figure F. Solder the wire to the PC board on the
component side only.
r Insert the 8-pin transistor socket into the PC board
holes from the solder side as shown in Figure F.
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 Insert the two fuse clips into the PC board holes
on the component side as shown in Figure F.
Solder the clips to the PC board.
r Solder the 11mm spring to the solder pad on the
top legend side of the PC board as shown in
Figure G.
