ENGLISH: It is a circuit that uses two transistors in a novel configuration. Minimize distortion to the point of being undetectable. It combines the properties of a preamplifier and an operational amplifier. The output level is regulated by the gain control and not by a volume potentiometer. It has two inputs, one non-inverting and one inverting. The latter makes it possible to create, for example, a very simple and very pure mixer. As a preamplifier it is ideal for microphones because the output signal is strictly identical in shape to the input signal./////////ESPAÑOL: Es un circuito que utiliza dos transistores en una configuración novedosa. Minimiza la distorsión hasta el extremo de ser indetectable. Combina las propiedades de un preamplificador y de un amplificador operacional. El nivel de salida está regulado por el control de ganancia y no por un potenciómetro de volumen. Tiene dos entradas, una no inversora y otra inversora. Esta última permite crear, por ejemplo, un mezclador muy simple y muy puro. Como pramplificador es ideal para micrófono porque la señal de salida es, en forma, rigurosamente idéntica a la señal de entrada.
