[TenTec] Yamaha CM-500

[Dr. Gerald N. Johnson]

It probably was dynamic at some time, but is electret now. I don't think 
I have the packaging mine came in any more. I bought it from Sam Ash 
Music for a really good price last August 19, 2009. And their web page 
today still says its a dynamic microphone.

everything else on line about it that was copied once.

Its changed, its different than it was. Its electret and mine came with 
a battery box for bias if the input it is used with can't supply bias.
