Hi, I have three Oktava MK319 mics that I did the usual modifications to: replaced caps, some resistors, removed the inner screen in head basket, applied silicone to dampen the body and head basket, removed the resonator disc from the capsule, removed the switches. I can't remember if I changed the FET or not, as this was three years ago. For a while, I was pretty happy with them and I used them in many different situations but they were never my favorites. (current favs are a modded CV4 and a CM7GTS/M7.
So the other day I decided to install a M7 capsule and wire up one of the switches so I could get it to be both cardioid and omni. I only did a quick test so far and it seems to work fine and sounds good. But I have a question.
I'm curious about the polarization voltage on the capsule. Being a FET mic, I believe the voltage can't be any higher than 48V. What effect does that have on the capsule? I've read that higher voltages will decrease the noise floor and decrease the low end. Is the only possible issue an increased noise floor and possibly more bass response? The U48 only had 52V and sounds great.
thanks for the info.
