FIELD: acoustics.
SUBSTANCE: invention relates to high-quality audio amplifiers. To realise the technical result, an amplifier is proposed without general feedback, including a pre-amplifier 11, a voltage-controlled current source with a resistor 12 at the input, a terminal amplifier 9 with a resistor. The reduction of distortion and output resistance of apparatus device is therein provided by the introduced resistor 14 with a resistance equal, minus the resistance of the resistor 12, a fraction with a numerator - the product of the resistance of the resistor 12 reduced by one by the steepness of the amplifier 11, and a denominator - the sum of the return resistances of the input amplifier 9 and the resistor 10.
EFFECT: reduction in the distortion and output resistance of the apparatus.
