Projects > Ioaudio MK47 Tube mic
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.

What tube is used?Or, what tube is this wired for?
Hi Dave,
Thanks for pointing out that I forgot to include that info! I just added it to the list of components above.
Just curious, which mic body and capsule are you planning on using?
Can you direct me to IOAudio – I’m having trouble finding.
Thanks
