Last winter, I bought nearly 1,000 cores from Dexter Magnetics, near Chicago. Good service. Use the part numbers in Appendix One of my tutorial. They're an industrial vendor, don't know their minimum

I used to think amidon was expensive too, but just last week I ordered some cores from them that we're almost 30% cheaper than mouser. I was pretty surprised. It's probably worth checking prices agai

Which cores were that? Maybe they have been doing some comparisons recently since Mouser, Digi-Key, Arrow, etc have been well advertised on many forums. The most overpriced has always been Palomar Ca

I don't think it was entirely a "scam" on the part of Amidon. When you think about it, FT-240-31 is easier to know "Ferrite, Toroid, 2.4" OD material #31" is a lot easier to remember than "2631803802
