[Harp-L] Astatic crystal elements

[bad_hat@xxxxx]

So I just went through a bunch of harmonica related stuff and tripped 
over what I think are 6 Astatic crystal elements and 2 of the ceramics. 
It might actually be 8 crystal but I have not delved into them yet 
Bought new from Astatic before they were discontinued.  No idea if they 
are still alive.  Short of soldering them into a shell anyone have any 
ideas about how to safely test the output?  I seem to recall that 
measuring their resistance is a very bad idea.  NOS in the original 
boxes but not stored in a humidity stable environment.
