Interesting to note that the second part of that rusty choke article poses some questions about the cores, and there never was a part three to answer them. What I'd like to know is if the boards had been powered up before the corrosion appeared or not. It seems to me there must have been something electrolytic between the copper and iron (likely just some ambient moisture that got trapped) that, when the board was powered, caused the iron to galvanize to the copper. Anyway, was an interesting article.
I'd like to see just how much of a difference the Super Alloy chokes make in the board's performance.

Just a guess? Permalloy or mumetal.
Permalloy probably, cause it's cheaper, though mumetal looks to have about 1.5x more permeability. I gues they could use supermalloy if they're going insane with these, but it'd almost certainly be cost prohibitive.
