Musta been all those drunk inauguration parties that needed access.  I'm sure the problem wasn't on my end.

Maybe it was a conflation of "ferrite" with "fair, right".

I've got a 2" toroid on order from Mouser -- 40 ohms at 1 MHz. It will go inside my next mic preamp. Mouser carries many Fair-Rite products.
