Hello!

I have a pair of B&O BM3's. My problem is the low output from them, and I've read that this is the case with most old ribbon mics especially B&O's. Both mics sounds the same and have the same output, so my guess is that they're in normal condition.

Questions are:

Do I just need a AEA TRP with 80 dB quiet gain?
or can magnets lose strenght with time?
or have the ribbon lost its tension?

Maybe I can modify them by replacing the original transformer with a new one. I read that ENAK is putting in new Lundahl transformers in Old ribbon mics.

All inputs are more than wellcome!
