The invention provides an AB-class audio amplifier power protector, comprising an aluminum wire resistor for detecting currents of output tubes, a micro-current source circuit of a low-voltage transfer current and a current threshold detection module as well as a module for controlling an output drive current. The audio amplifier power protector is mainly characterized in that the aluminum wire resistor is used to detect an output current and starts an overcurrent protection function; and the differential pressure of output tube CEs is used to control the output overvoltage protection of the output current. An output overcurrent protection module mainly uses the reduction voltage of the current of the output tubes on the aluminum wire resistor to actuate the micro current source output current to be enlarged; when the current is more than a threshold value, a current mirror works and outputs part of drive current after the output tubes are pulled off, thus realizing the restriction ofthe output current; and the output overvoltage protection uses two divider resistors which are connected between the output tube CEs in parallel, when the voltage on the low resistor is enlarged, theoutput current of the micro current source module is changed, thus reducing output of the drive current, thereby avoiding that the output tubes output too large currents when the differential pressure is too large.
