More on the Oktava Transformers
Here is a little diorama of the Oktava ribbon mic transformer from the bunch we bought from Oktava. Quite a long time ago, Oktava ran out of aluminum ribbon material so we sent them some for free so they could restart production, and they sold us some of these transformers as part of the deal, in case we liked them. In retrospect it appears that the material source went to China from Oktava - at least that's the way it looks to me when I examine one of the Alctron "Cosmetic Case" double ribbon microphones, which has a ribbon motor that looks like it is straight out of an Oktava ML52.
That mumetal "can" is something to behold; not very pretty, but functional, and that stacked silicon steel toroid with about 55 layers is another interesting solution.
We always purchase what we take apart and expect that others will do the same. This needs to be said because we occasionally get other manufacturer's gear in to check out which we do not disassemble.
