Sine wave generator with low distortion

The following construction of low-frequency harmonic signal generator was necessary for debugging and measurement of audio amplifiers and other circuits, working in the audio band. The circuit is used in conjunction with low frequency (million) a voltmeter,oscilloscope or meter bias and provides an invaluable tool for checking and debugging all levels of the amplifier chain.
