This question should be easy so here goes;
When building up a usable high quality mics from one of the small electret
elements... What should I do to insure the lowest level hum... I mean other
than good shielding...
Do they have less AC hum when the batteries are placed closer to the element,
in the same shielded housing or can you provide the DC from a remote
shielded box and what is a good working load on these things???
thanks in advance
