Yes, I mentioned, but also never tried.
They sell the separate capsules here:

and here:

Might look expensive, but check this big tube mic that uses this exact same capsule:

Might be an indication that they really sound good. One would have to try and let us know, as I don´t know anyone that has this kind of russian mics.
