ASSEMBLE COMPONENTS TO THE PC BOARD
Figure B
Diodes have polarity.
Mount them
with the band in the correct direction,
as shown on the top legend.
Figure C
Electrolytics have a polarity
marking indicating the (–) lead.
The PC board is marked to
show the lead position.
Wire 1” - Cut a 1” wire and strip
both ends. Solder one end to
the PC board marked (–).
Wire 1” - Cut a 1” wire and strip
both ends. Solder one end to
the PC board marked (+).
