Nevaton.eu is the European distributor's website, so I think I would go with the Russian specs. I can check on this and see what I can find out for sure. I can say with reasonable certainty that they do NOT draw 10mA.
Incidentally, please excuse the sales pitch here but our US distributor is currently clearing out all the "NOS" Nevaton so there are some pretty nice prices to be had right now on MC49 card, MC49 omni, MC416, MC51 and perhaps several others (no 400s though, sorry). Email me if interested - dirk@bigpurpledog.com - we may even be able to arrange for a 1-2 week demo as well...!
To toss in my 2 cents (or rubles, as the case may be) I would also pick a set of Nevs as my desert island pair. I've always loved the MC49 and they are a fantastic all around card. They would probably be my #1 pick, BUT a gig we did recently may have shifted me to the LDs...
We did a multitrack of a violin performance/presentation and used mostly Nevs. Some MC49, MC51 and MC416 in various roles in a close miking situation and we used the LDCs across the front of the stage for the fiddle player(s) and the discussion/narration. After the performance, the head of the local youth orchestra couldn't get to me fast enough to ask what in the world the mics were that we used! He said he was amazed at how natural they sounded both on the violins and on the voice parts! Before I could say anything, the house sound guy standing there next to me chimed in and said "yea they did sound great. I actually ran all of them completely flat from the start and didn't touch the EQ all night.". I thought that was pretty amazing. Listening to the roughs a few weeks ago in the studio the client was extremely happy with the sound of the strings and I hadn't put any EQ or effects on them at that point.
So long story short...after that experience I might have to go with a pair of MC416.
