The PA1X200 amplifier kit provides the builder with instructions covering how to build the kit as well as the underlying theories behind it. Some of the topics covered include boost and invert DC/DC converter theory as well as the DC/AC converter theory. The finished unit does not include a case (the builder needs to supply it). This kit is an updated version of the kit featured in the April 1997 issue of Electronics Now.
