Although it *is* a bit small for my app, I'd like to perhaps buy
a few of them anyway. They're outstanding, cheap toroids.....
Where exactly might I find this?? I realize you're in Australia,
but I'll bet even with shipping, they're a helluva lot cheaper than
"real spun toroids."
I guess they're completely sealed at purchase, then?? I'll bet my
upcoming coil would be awesome with three or four of those on top, and
would look cool, too.
