The fact that a series resistance removes the bumping would lead me to
believe that it is in fact a resonance condition. The resistance is
critically damping the circuit. Now the only question is: what is
resonating at such a low frequency? The supply line circuit? The HV
transformer and main cap? Or some other combination?
