The classical Cockcroft-Walton multiplier circuits widely described assume a sinusoidal (i.e. symmetrical) drive waveform but in the particular case of TV line output usage, the input waveform is highly assymmetric, i.e. (relatively!) low amplitude, long duration forward scan and high amplitude, short duration flyback. This results in e.g. the typical well-known CTV-usage "tripler" actually being a Cockroft-Walton quintupler, and so on.
