In one of the oldest topics in this forum dealt with the
modification of the microphone Samson 01.http://www.audiomastersforum.net/synforum/10/topic-10663.htm
I replaced the FET on k170bl (less noisy) and it is a little improved the situation.
But, unfortunately, I did not understand what was done next:
"So now I have an impedance converter with a higher value capsule load (more voltage output from the mic) and a quieter FET. So the tradeoff between higher noise from the load resistor and the quieter FET sort-of balances out, but we have more output from the capsule (there's plenty of headroom, so no problems with this), and there is now a quieter, smoother BG, sound from the mic. "
Huge request to all to Steve G personally explain, please, if you remember it.
I did not understand English, sorry.
