The amplifier comprises instantaneously interruptible power source (I<2>PS) for producing a precise AC output voltage. A continuous mode I<2>PS can be built using only 7 power components, including two inductors and an output capacitor. The I<2>PS can instantaneously interrupt the correction and become idle. The inductors each attain a corrective current and provide a return voltage. Two switches are separately coupled in series with the inductors for selectively applying the respective corrective currents between the power supply and the output capacitor. Two diodes limit the return voltages. A converter converts the supply voltage or an internal voltage into an internal supply current. A fine amplifier can employ two low power transistors to rapidly deliver a fine current to the output capacitor. This dramatically reduces output noise and improves accuracy. The converter and the fine amplifier can be combined or used separately. The I<2>PS having unity gain is most accurate and requires a simple preamplifier.
