ASSEMBLE COMPONENTS TO THE PC BOARD
Figure B
Electrolytic capacitors have
polarity.
Be sure to mount
them with the negative (–)
lead (marked on side) in the
correct hole.

Figure C
Use a discarded resistor lead
to form a jumper wire.
Figure A
Mount the transistor with the
flat side in the same direction
as shown on the PC board.
Solder and cut off the excess
leads.
SPK - Speaker: Cut two 4”
wires and strip 1/8” of insulation
off of both wires. Solder a wire to
each lug of the speaker and then
insert the other end of the wires to
the PC board in the place shown
on the top legend.
