Abstract

Sistema de circuito en contrafase en un amplificador de corriente continua equilibrado para amplificar voltajes desde un suministro cuya salida equilibrada varía en forma en contrafase con respecto a tierra y también varía en fase con respecto a tierra, caracterizado por un par de dispositivos de descarga electrónica que tienen sus rejillas conectadas con la salida de dicho suministro y los cátodos conectados entre sí y una resistencia que conecta dichas rejillas y que tiene un punto intermedio conectados a dichos cátodos.
