RCA PB-90 Velocity Microphone |
This is the RCA model
PB-90 ribbon velocity microphone from the early 1930's.
The PB-90 was one of the first velocity microphones made by RCA and may have preceded the famous 44 series. A 1936 catalog entry shows a somewhat later version of the PB-90, advertised as being suitable for high quality public address applications at about 60% of the price of the 44-B model.
