Re: [Harp-L] Mic element question

Hi, Mike -

You CAN push an old crystal over the edge this way - with a truly good  
cup you can hyper-extend the diaphragm and in the case of the crystal,  
break the center pin's connection to the crystal itself. I don't  
believe you can damage a CR or CM this way. They are so much more  
robust and the pin is free to move as far as it wants - simply between  
the coils. However if an element is old and some corrosion or foreign  
material has made its way into that area, I'm not surprised that  
you're hearing strange noises as the clearances are very small. It is  
unlikely it is the wiring, which wouldn't care how well you cupped.  
Your element CAN be repaired. If it is a really good one, it is  
probably worth it though it won't be cheap. The world expert in that  
field is Chuck Gurney: cgurney@xxxxxxxxxxxxx

Subject: [Harp-L] Mic element question



Hello all,
 I was wondering, is it possible to damage a C.R. or C.M. element by  
playing big low end chords with a very tight cup on a bullet style  
mic? I've got a C.M. element that seems to malfunction when I play  
that way. Or should I be looking at wiring, or some other component of  
the mic it's in? Thank you in advance for any suggestions.
