Transformers for U47/U67/M49/M50 and other Microphones

Thank you Dany. I search and evaluate smaller size cores to use in both BV13 and T14. Once I find a good solution I will let you know.

Best, M

Hey all
Here are some audio comparisons of  AMI, SAMAR,and Ioaudio  trannys tested in my own C12 and U47 builds.  I recorded the trannys in a bunch of different configurations which are explained the audio. I don't want to say too much to influence peoples findings although it's safe to say the differences are pretty obvious in that the Samar transformers have much less saturation making them more sound more clear and Hi Fi The Ioaudio and Ami were both more colored but both are cool sounds it just depends on what sound your chasing.
Enjoy!

I'll  copy  my reply from OPR's thread in the microphone section.

C12 first.
I only listened to the (separate) voice and acoustic samples.

Wow. Yup, the difference is pretty obvious. Samar is much more hifi sounding. It sounds more extended, in any case in the lows (my ears took a serious blow after a hearing accident this year, so I'll refrain from the top treble range) and it sounds cleaner, too. I hear a slight scoop in the mids, but that is to be expected from this type of mic. Esses are fine.
AMI sounds lofi in comparison; more middy (and subjectively trebly maybe) and more grainy. Esses are a bit sibilant. The added midrange could be of use, though.
I do like a little character, but here I prefer the Samar.

I'll add that the C12 with the Samar sounds clean(er), but certainly not sterile.
We had a discussion about vintage character, back on page one, which might be interesting to re-read.

I must say I'm impressed with the Samar in the C12.
It looks huge and sounds likewise.
