I agree with Scott. I had a discussion with Mr Neve about this some years ago and he does know better, he was well aware that his observation was being bent out of shape to justify things that weren’t real. In this case, in-band behavior influenced by the edges of an out-of-band resonance. Modern transformers (with high permeability cores) in particular can exhibit behavior that isn’t captured in the classic models.
