Electronic amplifier device characterized in that it is constituted by an induction coil that through a switch and potentiometer connects to a first amplifier step with resistance which in turn is connected by a capacitor to another analog amplifier step that is connected to a winding of the transformer whose other winding is in series with the speaker; completing this arrangement the power supply and filament heating circuits the outlet with the outside and the derived terminals for the connection of the device to the turntables and radios with which it is used; in addition to its primary application to the telephone as an induction-driven amplifier.
