Amidon doesn't MAKE these parts. They BUY stuff, put their own 
part numbers on it, and sell it at OBSCENE MARKUPS (typically 4-
5 times their cost).  

I've helped organize group purchases for several ham clubs 
(others have done the real purchasing and distribution work, 
I've done the pointing). Charlie is right -- study the Fair-Rite 
catalog (that's who actually MAKES the parts you want) and learn 
their part numbers. Or see Appendix One of my tutorial

http://audiosystemsgroup.com/RFI-Ham.pdf  

for part numbers of some parts useful for chokes and 
suppression, AND a list of good industrial vendors in the US who 
sell at prices FAR lower than Amidon or Palomar or Bytemark. 
Those good vendors include Newark, Allied, Lodestone, and 
Kreiger. 

Last I heard, minimum order from the factory (Fair-Rite) was 
$500, and you MUST buy in box quantities. Their 2.4-inch toroids 
are packed 100 to the box.
