This project is a 2 channels amp meter. Those channels are completely isolated up to 2000 volts.It provides auto detection for AC or DC current. The main part of this project is the current sensor ZMC10 a cool DIP 14, which supports up to 10 A. The current is measured inside by hall effect sensor and display data using a graphic LCD of the read current and max peek value, DC or AC

This article descripts, how I built amplifier from Mr. Marshall Leach known like “The Leach Amp”. I built amplifier from the original instructions on these pages: http://users.ece.gatech.edu/~mleach/lowtim/. Article about bulding of this amplifier I found later in journal A_Radio Praktická elektronika 11/2002. For many years I looked for construction of HiFi amplifier wit a good parameters, enough power reserve and simple construction.
