ABSTRACT:
Disclosed is an amplifier wherein, in order to prevent the mixing of hum and other noise from the ground potential of the amplifier, the driving power supply circuit of the amplifier is separated from the ground potential into a floating state. In addition, the overall capacity of the power supply is reduced.
