Pearlman Microphones TM-47
Cardioid Tube Condenser Microphone
Dave Pearlman’s TM-47 is a tube microphone modeled on the Neumann U47.
The capsule is Pearlman’s version of the K47, manufactured in Southern California. Like the original K47, this capsule has a single backplate measuring 34mm O.D., and uses diaphragms made of 6-micron Mylar, metallized with gold.
The circuit is as found in the U47, with either a Telefunken EF12 or EF14 steel tube. The transformer is described as a historically accurate BV8 type. The output capacitor is a vintage-style “paper in oil” type.
We will provide more details about this microphone when they are made available.
