Power output
45 watts per channel continuous from 20Hz to 15kHz. 1kHz total harmonic distortion typically 2% at 45 watts, below .05% at 0.1 watt. Approximate actual power available at “clipping” 50 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
