why must large, high-Bsat magnetic cores be so hard to get?
It's looking like we might be spending $1500 to get thirty-two cores because the only company that makes these has a minimum order quantity and they're all made to order, they don't stock the huge ones normally
at least if we do go this route (the alternative is $800-odd for only exactly what we need right now, with no spares) we'll be getting molypermalloy cores with a μ of 26, rather than the 14 or 19 of the ones they have in stock.
