Building

I strongly recommend using a good quality soldering iron and only electronic solder for constructing this
project. The soldering iron should be at least 50 Watts and should provide enough heat so that the
solder melts quickly. If you have not built a project before I would urge you to watch one of the many
YouTube videos on soldering and kit building. Practice if possible.

** Radial lead electrolytic capacitors may be used to lower the board profile.
Use provided tables in Appendix B to help identify resistors. It is strongly recommended that
You obtain an inexpensive DVM and measure each resistor before placing it into the board.
