Many years ago [as in maybe 54], I needed a ferrite core for a 4:1 
balun.  DX Engineering hadn't been invented then.  I drove over to 
Amidon [N. Hollywood/Burbank-ish] which turned out to be a suburban 
house.  A fellow, who's name was Amidon opened the door, installed me in 
a living room filled to the brim with all sorts of boxes and stuff, 
rummaged around in a bedroom and finally came up with the toroid core. 
He wanted a lot for the core, in fact more than the 16 year old had.  He 
finally asked me where I had come from, and when I told him S. Central 
LA, he gave me the core.

The balun didn't work, probably because I wound it wrong.  I'm really 
surprised they are still in business.
