The theoretical aspects of current dumping are discussed. An example of a high power amplifier has been built with very cheap and slow output transistors. It uses a Class-G configuration to increase the efficiency and has no quiescent current. As a consequence, the power block introduces a lot of distortion. Yet the distortion of the whole amplifier is very low. Its characteristics are an output power of 500 W in a load of 8 ohm, a slew rate of 25 V/µs, a high power bandwidth of 32 kHz and a harmonic distortion of 0.0024% at 500 W 1000 Hz.
