The following information is to supplant a future article about CNC Milling circuit boards using various software packages such as G Simple and Carbide Create. Our first example was an samll audio amplifier stage now we will tackle something more complex. we shall now take a standard circuit element known as the Plessey Amp which is a two transistor bilateral circuit and develop milled circuit boards for both a Through Hole and SMD version.
