Abstract
A vacuum tube amplifier is formed of a vacuum tube having a cathode, a plate, a grid, and a heater to radiate electrons from the cathode. An input signal is supplied to the plate, an output signal is obtained at the grid, and a predetermined low voltage is supplied to the heater. The voltage supplied to the heater can be low, thereby significantly decreasing an overall consumption of electric power for the vacuum tube amplifier.
