soldering.
ASSEMBLE COMPONENTS TO THE PC BOARD
Care must be given to identifying the proper components and in good soldering habits. Refer to the soldering
tips section in this manual before you begin installing the components. Place a check mark in the box after
each step is complete.
Figure A
Electrolytic capacitors
have polarity. Be sure to
mount them with the
short negative (–) lead
(marked on side) in the
correct hole.
Warning: If the capa-
citor is connected with
incorrect polarity, it may
heat up and either leak or
cause the capacitor to
explode.
Mount the electrolytics horizontal to the PC
board. Bend the leads at right angles and
then insert the leads into the PC board.
Figure D
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.

Cut one 4” and two 2½” wires
and strip ¼” of insulation off of
both ends of the wires. Solder
these wires to the points J1, J2,
and J3.
