The U77 High End Classic Tube Microphone is GERMAN DESIGNED, GERMAN MADE, IN GERMANY BY HAND with a GERMAN MADE, TRUE M7 Capsule made in BERLIN.  some parts and accessories of the U77 are also built by hand in sourrounding areas of Eastern Europe.

 The U77's tube is a NOS hand tested 5703 Raytheon military lamp with extremely low noise and very long operating life. The parameters are closely related to the legendary AC701K, however the noise floor is a marked improvement over the AC701K. The capsule is our exact replica of the M7 utilizing the Berlin "double ring type" and is built, skinned and tuned by hand in Berlin by our expert German capsule builder.  u77_kit.jpg
