Abstract : A novel, lightweight power amplifier has been developed for use with the NRL electrochemical recording paper and multifingered stylus. It consists of an amplidyne excited by a field control amplifier and negative feedback loop. When employed with the proper external limiting resistor, it is capable of providing acceptable current linearity over most of the dynamic range of the paper and will accommodate a variety of stylus widths. The frequency response is flat below 40 cps.
