I don't know of a new supplier personally.

I know the price seems ridiculous when compared to what these crystals 
cost this person - BUT - Fair Radio DOES have the 14MC crystal on their 
site.  It is $12.

They are probably the spare parts that Fair bought up when they bought 
the R-390A parts they have been selling for about 7 to 10 years.  I've 
gotten NIB IF cans from them over the years too.
