[Elecraft] D-104 Mic Element Replacement

[Tim Tucker]

In the original post, he stated that he specifically did not want an
electret element, has found the dynamic replacements and is not interested,
but wants a crystal element replacement.  Most of the links offered do not
offer what he is looking for.  So I stand by my original statement with the
following qualifier:  There are probably some old stock or salvage crystal
elements out there somewhere, but good luck finding them.
