His post was an attempt to output a subharmonic without the
oscillator. There are better ways to handle such a scenario.
For example, see my boom-box machine (circa 1979)...

Cool; a dozen quad LM324s, 48 crappy opamps. LM324's show visible sinewave
crossover distortion at 60 Hz.
One question? Who would put a circuit like that, grossly distorting, with
hundreds of parts, consuming about 5 watts, into a boom box?
