according to Jakob Erland, this circuit has nothing in it that can produce hum,and i agree with him.
but i ask everyone again,
given
1) the connections are tight and good,
2) there is no ripple from the phantom dc rails
3) the 2 connections on left of schematic are joined to face(top) and backplate(bottom) of capsule
can this circuit cause hum of itself at the input of a preamp/mixer
thanks very much. reuben
