Good info Tom, I'd like you to try -61 material, but I don't have anything
but T50 in that ferrite.

Hi Harold,

Well, I'm curious about -61 too. Turns out I have some FT50-61's (or
so claimed by Baggy Bob...), and I have FT50-67, FT50-68, FT50-43,
T50-1, T50-2, T50-3 and T50-7 to try for comparison. Unfortunately,
we're out of T50-6, but maybe I can arrange a test on a different -6
against the same size -2, at least. Not sure if I'll get to the coil-
winding and testing today, though.

Cheers,
Tom
