The MK47 kit is a clone of the Neumann U-47 tube condenser microphone circuit. It includes IOAudio’s reproductions of the original Bv.-08-00 transformer and VF14 vacuum tube. The kit contains all of the components needed to build the microphone head amplifier; builders must also source a microphone body, capsule, and power supply.
