Figure A
Cut a piece of bare wire long
enough so that 1/4" of wire
passes through each hole in
the PC board after the wire is
formed
(provided
in
second package).
Figure B
IC
the
Socket
Insert the IC socket into the PC
board with the notch in the
direction shown on the top
legend. Solder the IC socket
into place. Insert the IC into the
socket with the notch in the
same direction as the notch on
the socket.
Figure C
Flat
Notch
Mount
the
transistor with
the flat side in
the
direction
shown on the
top legend.

have
a
marking on them indicating the
negative (–) lead. The PC board
is marked to show the lead
positions.
Mount the
capacitors
horizontal to the PC
board. Bend the
leads at right
angles and then
(–)
insert the leads into
the PC board.
