Lomo MKE100 48 conversion advice

Hello!

I am new to this forum and also pretty new to microphones. I have four Lomo MKE100 condensers that my friend's dad wanted to use at his work as stage condensers. They run off of two 1.5V batteries but they want them as 48P. I was wondering whether anyone has a good schematic to convert them to 48P?  I know they work from batteries for years but still, need them done as 48P.
I found this therad: http://groupdiy.com/index.php?topic=41382.msg514200#msg514200
But can't log into Twin-x so can't see the schematics.
Also found this: http://groupdiy.com/index.php?topic=52627.0

But everybody there seems to have a different idea how to do it and no definitive solution.

Please, I really need someone to help me make them run from 48P. I have all the parts and tools needed

I was in this dilemma, and from CemD's suggestions, I built the Lomo 19a19 circuit in a pair of mke100 and they sound pretty good. I imagine if you are doing them for stage sound, power supply boxes might not be ideal.

I found These drawings in my files. Hope they help. I just made mine into 19a19 circuits instead.

Here's another version
