Power output
30 watts minimum continuous at 16 ohms from 17Hz to 20kHz with less than 1.0% total harmonic distortion. Typically below .005% at 1 watt. Approximate actual power available at "clipping": 32 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
