Neumann M50b Triplet refurbished by BLUE #41/42/43 (Used)

Very nice condition triplet of Neumann M50's, refurbished by B.L.U.E. microphones. Includes Blue psu, wood box, cable and flight case.

These M50's were refurbished from the ground up with new PSUs, new electronics (including transformer), NOS AC701k, NOS Neumann gold-sputtered matching diaphragms, and original spherical capsule mounts.
They were refurbished specifically to be a matched set that would be an accurate representation of the original M50 with modern reliable components.




The M50 is a pressure-type microphone with non-directional characteristics. After its introduction in 1950, the outstanding characteristics of the Neumann M50 made it a standard for the recording of symphony orchestras. A pair of M50's were famously used on one of the very first commercially available stereo recordings: 'Also Sprach Zarathustra' by Richard Strauss, released by RCA in 1954. This performance by the Chicago Symphony Orchestra under Fritz Reiner is still available today, although instead of open-reel tape, you can now hear the brilliance of the Neumann M50 microphone in SACD format.
