ECM8000 circuit puzzle

(4)
By the way, DON'T TAKE YOUR ECM8000 APART. The wires from capsule in the nose to electronics in the fat body of the mic are too short to allow pulling the

Output gain in a Schoeps/Alice like mic circuit

(24)
... It's been demonstrated times and times that transmission line effects are negligible as long as the length is small compared to the shortest wavelength. At

Is IDSS = Max current from drain to source on a JFET???

(6)
Goran, I got it! I added a small 5k resistor R11, working as a voltage divider with the 100k pair, so voltage level at FET gate could be lowered below source.
