You can no longer get either the original crystal element or the ceramic

The dynamic is a whole lot smoother and less brittle sounding, but maybe
that's a bad thing in a pileup.


Hi,

You can install a Kobitone crystal element in the D-104 mic head,
Mouser.com P/N 25LM022
It has a raising freq characteristic similar to the old Astatic crystal
element.

Electric Radio Magazine, Jan 2010, had the how-to-do-it article.

I found this doing a Google search. They appear to be
available in several sizes and types and the company also
makes ceramic elements. I found prices varied by a 2:1 ratio
depending on who was offering them. Mouser had about the
lowest prices, only about $5 US each. I suspect these will
fit a lot of old crystal mics and make them useable again.
