hey-Hey!!!,
The shape of the curve containing a sine-wave shaped signal is about the same. Start from a DC idle point, or a zero DC idle point and take the second cycle under examination. It will be a material-dependant 'S' shape, give or take. Mu-metal will be thinner than M4, but with a peak roughly 1/3 the flux density for example.
Now the current cancelling SE will start from a zero flux point, rather like a current balanced PP. One can gap for a smaller DC tolerance and cancell only part of the power tube's standing current too. Or put a small gap in a PP OPT's stack. Given the benefits I've heard from gapping small signal Iron like grid chokes I am looking forward to having Heyboer build me some PP ls to run gapped cores with. Likely to be made with 49% Ni so that I can gap to the same initial permeability of M4 SuPerOrthoSil...:)
cheers,
Douglas
