The AMI U47 kits provide the framework for Neumann/Telefunken U-47 microphone projects. The kits include the headbasket, body, capsule mount, and AMI’s replica of the original transformers. The class kit uses the vintage Tuchel connector, while the modern kit updates the connector to a Binder 7-pin variety. Builders must source other parts, such as the capsule, tube, and power supply themselves, but AMI has provided a great schematic and BOM for a full U47 build on their website.
