Fair-Rite 2631803802 is the Amidon FT-240-31. Available at Mouser, Newark, Arrow, and other places. Mouser part # 623-2631803802. Mouser says they have 1589 of them in stock :-).
I have a personal cross-ref between some Amidon and Fair-rite numbers. Not sure if I'd get in trouble for publishing it (I remember when I got chewed out here for suggesting Laird/Steward equivs). I don't think it's a big secret - the Fair-Rite part numbering system for toroids and binocular cores seems pretty transparent. I like to use a white paint marker to put mix numbers on big cores as I unpack them :-) Tim N3QE On Mon, Aug 4, 2014 at 5:54 PM, Hugh Valentine <hsv...@juno.com> wrote: > K9YC touts the benefits of the 2.4" O.D.
