The FT-series of part numbers are PHONY part numbers,  dreamed up many 
years ago by vendors who have sold them to hams for very high prices.  
The ACTUAL part number for a #31 2.4-in o.d. toroid, as defined by 
Fair-Rite, the company that MAKES these parts, is 2631803802.  You will 
find that part number in Appendix One of my tutorial.  Kits and Parts is 
one of those high price vendors. Amidon may have been the originator of 
this scam. Palomar and DXE are in that league as well. They created 
these phony baloney numbers so that you wouldn't find the part from a 
real industrial vendor at one third the price.
