CKBK UM51 /w 8A17 Capsule Omnidirectional FET Condenser Microphone — 1973, USSR, 10B47 PSU

Up for sale is a very rare CKBK UM 51 FET condenser microphone, an exceptionally unique find. This high-quality microphone is known for its superior sound capture, rivaling even the famous LOMO tube microphones in certain applications. It comes with the original and EXTREMELY RARE 8A17 omnidirectional condenser capsule, designed by LOMO for the film industry, yet it also performs remarkably well in music recording. This particular UM 51 microphone and 8A17 capsule were produced by CKBK (Central Design Bureau of Cinematography / NPO EKRAN), not LOMO, under which UM 51 microphones were later widely manufactured. This distinction suggests that this set is from one of the earliest prototype series, with the microphone and capsule produced in 1973 with serial numbers 730005 and 730002. Such early versions have not been encountered before, making this pair especially rare and unique. The mic comes with a very well-built cable with a soviet military connector on one end, and a Neutrik XLR on the other. This mic really has a beautiful, warm, rich tone that is unlike any other mic I've used, and it's especially good on brighter sources or anything that needs more body and weight without sounding boomy. The mic powered by 12v phantom power. Optionally the microphone can be converted to standard 48v phantom power or water tube circuitry at an additional cost This listing includes: - 1973 Lomo UM 51 U1.1 FET condenser microphone - serial number 730005 - 1973 CKBK 8A17 omnidirectional diaphragm capsule - serial number 730002 - 4DIN/XLR and 4DIN/4DIN professional audio cables - Original CKBK 10B47 PSU - Original LOMO shock mount clip WORLDWIDE SHIPPING.
