ASSEMBLY INSTRUCTIONS
Be careful to properly mount and solder all components. Diodes, transistors and electrolytic capacitors are
polarized, be sure to follow the instructions carefully so that they are not mounted backwards. Check the box
when you have completed each installation.
Wear safety goggles during all assembly stages in this manual.
