I'm probably completely on the wrong track; but the 3340 is a triangle
core oscillator - there's a triangle waveform on that capacitor. If you
short it at certain points on the waveform maybe something weird happens
like an overshoot. Normally when you do sync on a triangle core
oscillator you have to force the comparator too.
So take a look on the triangle output and see what's actually doing
before the waveform goes to the tri to saw convertor.
