I have a pair of MXL V67N Mics and I like them.....but not enough to leave them alone . I opened one up: -The electronics are mostly surface components - There is a transformer (of course) - the Capacitor off the capsule looks good - A "larger" electrolytic capacitor; a 47uf 100v nichicon - A 'smaller" electrolytic capacitor 47uf 63v no sure the brand the cap is blue and the logo is a circle around an "M" - A ceramic capacitor; I have not idea about values brand etc. I've attached some pictures and I have 2 questions: 1. Does anyone know if upgrading the electrolytics will do much to the sound? 2. I have some ELNA R20 caps 47uf at 50volts. Is the voltage in this mic very high? I don't want to blow up a cap, but I am guessing it should be fine to a least replace the 63volt cap with this 50v one....
