Patrick,

There have been found one or two souces of low frequency crystals.  Most
manufacturers will not make them any more.

There have been reports of one fellow in Mexico I think, but I don't have any
info on that source.

The only other one reputed to make low frequency crystals is:


Universal Crystals Inc.
Jim Little
Private Company, Headquarters Location
5407 Payne St., Shawnee Mission KS 66226, 
United States
(913) 334-6254,
Line of Business: Manufacturing: Quartz crystals

Here is the source of my information:

Phil and others,
I have just gotten the following from Glenn Nash about a source for low
frequency crystals:

  "Mel" is the guy at:
www.mhelectronics.com.  (800 643 9825)

 Mel said that the best guy on the planet for those is : Universal Xtal in
Kansas City, phone 913-334-6254 ask for Jim Little.

 I called Little and lo and behold he says he bought up just about every low
frequency xtal blank in the US and is at this very minute cranking out a bunch
of 455KC types. They are a bit expensive, around $50, but less than half what
International Xtal gets for their low freqs.

Try to contact  "Mel" and let us know what you find out, please.

Roy
