I tried a RS electret element I have here and the audio is distorted and weak
- do I have a bad element or am I doing something wrong?  I wired the
element directly to the mic wires bypassing the transformer in the mic with
no cap or resistor.  The red wire and audio to pin 1 and the ground to pin
7.  Guess I'm clueless when it comes to electret mics!
