... Also, I'm reminded of playing with my Eico 377 signal generator (classic Wien bridge, dual air variable cap). On the lowest frequency band, it's kind of unstable (it's working with ~10M resistors!), and has a long time constant, so it's easy to make it 'bounce'. Set it for a low frequency and wait for it to stabilize, then yank the dial up to a high frequency.. the waveform overshoots, rebounds and stabilizes. Or dial it up slowly, and the amplitude tracks higher than normal until you stop.
If drive power is supplied by the stored electricity, then it's just a capacitive transformer -- nothing wrong with that, and saves the difficulty of a wide range electrical converter.
