[AMRadio] RE:Microphonic Caps

[John E. Coleman (ARS WA5BXO)]

I really wonder how it might sound if I were to attach some kind of a
diaphragm to the side of one of those little brown ceramic caps (.005 - .02
uf) and glued the other side down to a piece of hardwood and put about 50
volts or so to it through a 5000 ohm resistor.  I'll make the whole
microphone case out of wood in lined with aluminum foil with slots cut in
the front.

What do you think Bill?
