Where exactly do you get ferrites for power supplies. So far i've found a few places (good deal on RM10 cores and PQ40), but is there a place that sells a wide range of parts for a decent price? Or someplace that has some options between RM10 and PQ40.
Really, i'm looking for something in the RM12 size or so.
