TT does not specify the manufacturer of the electret element supplied in the
1201 T-kit.
However, it bears an uncanny resemblance to a surplus
ATT cell-phone microphone sold by All Electronics
of Van Nuys Califronia.
About a year ago, I bought a box of those ATT mics and dismantled them for
the electret element ( for some other projects of mine ) .
When I opened the TenTec kit , I noticed that the mic element
looked EXACTLY like the one in the ATT microphone.
Same dimensions,
same aluminium case,
same pattern of holes in the front,
same terminals on the rear,
same little green printed circuit board on the rear,
same traces on the circuit board,
and so on ...
Perhaps the mic element was manufactured by Electro Voice,
since TT was founded by an engineer from EV,
and is right across the street from the TT factory, there in Tennessee. And
they are probably still good buddies....
And the 1201 manual brags that the 1201 microphone was characterized at the
EV facility, right across the street.
I suppose it is also believable that ATT would buy their
mic elements from a company like EV .....
Maybe we oughta have a look at EV's web page
for info on their microphone elements ....
The mystery deepens....

p.s. Did you build the TT-1201 kit ???
