Anyone tried to attack one of these?

Electret, circuit probably similar to BM800. Would like to try it with some better capsule. I have one micro k67 laying around. I guess 36v from phantom will do just great as it will operate from close proximity, i don't need it crazy sensitive.

Attached image is this old russian micro k67 model.

Ok, so i bought this for donor body. The microphone does not work actually, as it has no circuit inside, the electret capsule is just connected to output xlr.  :eek:

The capsule fits perfectly

I used Cchoctava circuit from this link:

It fits no problem, and there is a lot room left:

U87- Green
My Mic- Red

That low end dip comes in handy with PE. And i used 0.68uF capacitor instead of 2uF for C3.

If you look at it with a phone, hold the picture, open in a new tab, or save as. Right click on a computer...
 
Unfortunatelly, the sdc capsule is too sensitive to breath moisture, and didnt work well. So i went with 797 audio's c12. It just fits under the cap. I need to work on shiending though.
