Unless I missed it somewhere, there isn't enough data in that link to judge how useful the cores are, or even what they are. Z by itself is not very meaningful. For example, 500 ohms of reactance or

I'm quite happy with the test results for Laird #35 toroids. The price is much less that Fair Rite for a comparable part. From my point of view, there's no need to stick with IBM, GM, etc. Chuck ____

I've had samples and a catalog from Stewart for years, but there's not nearly enough data there on which to base a judgment. Like Carl and Tom, I see no value in "much cheaper" for a product which th
