ABSTRACT:
An audio amplifier and power supply having a power transformer with power supply and control means to provide pulses of electrical energy at a substantially constant supply voltage, with the duration of the pulses being dependent upon a value that is related to the demands of the amplifier. The transformer charges a power capacitor to a substantially constant voltage to supply power for the amplifier. The frequency range of the pulses is between about 400 to 2,000 cycles per second, with a frequency being at about 1,100 cycles per second in a preferred embodiment.
