Old Mics

[haijdkropwe]

I obtained two older condenser mics: MB Elektronik MB C540 and Preter UCM-1020.
Both run on battery power, Preter on standard 1.5V and MB C540 on stranger 15V (two) batteries.
MB C540 has a strange cable that doesn`t fit the mic inputs on my mixer.
Questions:
Does anyone know anything about these mics?
Is it posibble to use 48v phantom power with them?

Nobody knows?

You might try posting at www.gearslutz.com . There are a number of people there who know quite a bit about the more esoteric brands/models. Be patient, as they are pros who don't necessarily check the boards every day...

is it a tube mic, that needs special power supply?

 

[haijdkropwe]

No, it`s not a tube microphone, it`s a small condenser, with the battery cartridge inside.
I suspect it`s a mbho microphone that someone mentioned in this post:
http://www.homerecording.com/bbs/showthread.php?t=87866&highlight=mbc+540.
I found a few pages that mention this mic, one even has a picture: http://www.hestudiotechnik.de/image/microfones/mbc_540.jpg
As I don`t have the 15v batteries, I was thinking of using 48v phantom power on my mixer but I`m afraid it will hurt the mic.

Most likely the 1.5V one is an electret mic--leave it as it is.
I am sure it is possible to convert the MBHO into phantom. If I had it in my hand I'd tell you exactly what to do, but without seeing it and reversing schematics it is hard to give any advise.
