BV8 Tube Microphone Output Transformer​

The BV8 transformer is at the heart of the legendary U47 tube microphone.

The Crimson CT-BV8 is a modern version faithful to the essence of the original. It features a precision wound 6.5:1 turns ratio, and uses a high nickel alloy core material. This combination produces excellent wide band frequency response and extremely low THD values. The CT-BV8 has a 4 hole mounting pattern.

Custom variations for OEM applications include other core materials and winding interleaving options. Mechanical variations such as lead placement and inter-connection of the coils, along with graphic options are also available.
