ive got a ribbon mic and i can not get any audable noise out of it it is verry old a Electro voice V1 vilosity mic. all i can get out of it handeling noise.
Very often, because of contamination, the contacts lose conductivity, so first, disconnect the ribbon, and measure it. Then check the trafo for continuity, with ribbon disconnected.

Some good ribbons are in sensitivity between dynamic and condenser.
