A ribbon mic article

Happy New Year! Here's an article about the RCA KB-2C "Bantam" velocity microphone, which I just scanned from a 1950 issue of Audio Engineering magazine. Sorry for the large file size, but scanning at a lower resolution or in B&W (as opposed to greyscale) rendered some of the details illegible.

Thanx to PRR for the webspace.

It is revolutionary mic. Before this mic all magnetic structures was
divided to source (MAGNET) and concentrator (POLE PIECES)
in this mic there are all the some AlNiCo. It reduces leakage flux,
and then weight and cost.
All modern design mics are Bantam type from magnetical point of view.
