A simply constructed and inexpensive amplifier that exhibits unusually low noise is described. The amplifier is particularly useful in applications which call for large amplifications of very low- level signals. When variable gain and filtering stages are added, the amplifier provides flexibility, convenience, and performance comparable to the finest commercial units.
