Imagine my chagrin. I just took apart my D104 to check the markings on
the dynamic element I was sold in the '70s. It says MC-320, which,
according to a quick web lookup, is a crystal element.

This may be a good time to install that Heil element...

That would seem a simple and easy way out. just hope it sounds the same.
Crystal do not last but ceramic does. The response of the D-104

The handheld mic is supposed to have the same element, which is still available.
I would call them.

+22 dB at 3.2 kHz over 100 Hz.

The Heil is very different.

The classic D-104 sound is heard through a transmitter with cutoff's
and compression, and lots of garbling!!

One point, The amplifier probably lowers the 100 Hz response, so its
+12 at 3.2 kHz. without the internal amp.
