[QUOTE="Ampdog, post: 41758, member: 144"] Thanks Norval for exposing my incomplete advice as posted above. I was thinking rather 'local' (very). Andr? is invited for an outing to a restaurant of his choice for my leaving out his excellent product. [Not all 9 children, only himself and spouse (only one)]. As said, I concentrated on local manufacturer[SIZE=19px]S[/SIZE] Just to add to what Andr? said (carefully this time): I am not only thinking about impedance itself but the angle of such (i.e. 'reactivity - L or C component of which). I would guess that dipping somewhere to a low impedance is accompanied by some L/C component. The effect of that on an NFB amplifier could be far worse than simply not giving the necessary output. Reminds me that I should try to work out such an equivalent nasty load to use in Spice analysis. [SIZE=8px](The account for the restaurant - mine, of course.)[/SIZE] [/QUOTE]
