[QUOTE="Ampdog, post: 45276, member: 144"] Handsome, Thanks for that Lundahl quotation. Yes, inductance does change with exitation, but I am surprised that it generates what they say. (I respect Lundahl enough to accept that they will not talk nonsense,) In general, One must perhaps remember that a power transformer under load will suffer little from the inductance effects, as those should be quite small compared to the load impedance - heavily damped, to put it differently. I would expect there that filter input capacitance charging 'spikes' to be the ranking problem, especially when not 'cushioned' by a valve rectifier or other series resistance. These stray fields - jeepers - too many things in electronics require one to almost go to PhD level to get it right. (Could I not simply have gone to the profession of traffic cop to make life easy ...) This leaves one with a fair share (perhaps that should read 'unfair share') of problems to solve. [/QUOTE]
