...but if i speak strong at the mic the sound dissapear for some seconds and come back, maybe the Vgsoff of the fet i'm using...
i have downloaded the schematics,
Hi, i'm Marcelo from Argentina, so any contact MTG for repair is not the correct answer we are in another planet almost.The thing is, it started working ok (i don't remember if the sound was clear and open at first) but just in the cardioid position, when i switched to another position the sound was muted. At first i comeback to cardioid and the sound comeback too. Later it changed to actual situation, you have some seconds of sound when you plug it but 3 or 4 seconds after the sound fades and don't comeback.I've read lots of info here, i have downloaded the schematics, i'm an electronic tech and used to work with audio but NO EXPERIENCE WITH HI END MICS, sorry i'm not screaming, just to be clear. I understand the schems but i'd like some advice before to play with the circuit.I have the mic disassembled, the pattern selector section seems ok to me, without the capsule i have 51.7V at one wire and -51.5V at the other.AAAAHHH !!! the entire body of the mic came microphonic, i mean, i can hear the movements i make when the selector is at cardioid and omni, at 8 figure it's muted at all.I hope somebody experienced can give me a hand to fix this, thanks a lot in advance!!!Marcelo, LU4ENP
