Dead right-

I discovered that all I had to do to get an identical compoent from an 
Asian source was
simply to send a sample. These Chinese analyse the coil on an active 
instrument that
identifies every component including the core.

There is even a Tucson/Chinese company that does the engineering here 
and makes it
in China, 4 week delay for 1K of 'em, 2 weeks for a free sample.
