Abstract
An amplifier system including a vacuum tube amplifier having an input signal terminal, an output signal terminal, and an electron source, and a control circuit having an input terminal coupled to one of the input signal terminal and the output signal terminal, and for controlling a kinetic energy of electrons emitted by the electron source based on one of an input signal to the vacuum tube amplifier and an output signal from the vacuum tube amplifier. According to another embodiment, the control circuit may be for controlling an amount of electrons emitted by the electron source based on one of the input signal to the vacuum tube amplifier and the output signal from the vacuum tube amplifier. According to another embodiment, the control circuit may be for both controlling the kinetic energy of electrons emitted by the electron source based on one of the input signal and the output signal, and controlling the amount of electrons emitted by the electron source based on one of the input signal and the output signal.
