(10)Hey, thanks a lot for that that totally makes sense :) well understood there Yes some things have over 8 gain stages or even over 20! U47 seems a great
(5)Thank you very much for your response, Goran! And very sorry for the confusion on my last post. I shuold have read: "Signal at FET gate and source seems to be
(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

(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

(65)... I tried three solvent-based "paints" which allowed me to remove the coatings with Naptha. One was a conventional spray enamel, one was a spray flexible
(6)Thanks for those links Henry .... I'm looking forward to trying out the filter mod to try and reduce the zener/regulator transistor noise..... I've already
(8)So, yes, you must make sure that reflections and masking from the electronics do not interfere with any side of the capsule (rear is as important as front). In

(3)This is called feedback and is a common phenomenon when the sensitivity is too high.
(3)Awesome! Thanks, Ricardo. I have a bit of a service lead on the wiring so I can remove and install the switch, but it only ever dips down toward the XLR
(4)However, I think C4 in the schematic I linked you to, should be the same as C2, a 1uF [or less] good quality film cap. I have been able to get around 38 to
(9)Great question Jules! I will reprhase... Did anybody tried SimpleP48 circuit, with a non-internal FET capsule, like TSB2555B or TSB165A? As Jules said, this
(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.
(9)Hello, I vaguely remember this thread starting with questions related to quiet sounds being recorded in and outdoor setting. Here's something to consider: For
(71)No, I started this thread as a separate thread, though inspired by thread "very low noise microphone". I think that is the one you are thinking of. I didn't
