M221f Schoeps Transformer

[garp]

Hi everyone ! I have a dead 12v Radio france CMMT30 with sojie 7 pins connector that i am planning to convert as a point to point tube mic with a 6sb6 russian tube but i am lacking infos about the transformer used on them (Ratio etc). Do you know a source or a suitable tranny that i could use ? I also have a radio france ela 221 power supply for 6 ac701 mics ready to feed that project so the only concern is about the tranny at the moment

I don't know the ratio of a 221f either but I would think a Moby T14/1 is a good candidate for that circuit.

https://www.mobytransformers.com/t14-1and check the specs on your power supply as the 6s6b draws almost twice the current of a AC701...
So be sure your PSU can handle the increase in current draw.

As an alternative you have UTM: Microphone Transformers

Anything will be fine as far as transformers, from 7:1 to 15:1, dont worry
