Neumann U60 Tube Condenser Microphone #023 (Vintage)

Introduced in 1960, the Neumann U60 was a prototype of the legendary U67 microphone. At the time, Neumann microphones were named after the year they were released, hence the U60. Roughly 30 to 40 U60 microphones were produced and sent to select studios for testing. Before releasing the mics commercially, Neumann changed the name to the U67 to build on the success of the brand's popular U47, which was released in 1947. The U60 is an incredibly rare piece of audio history, making every mic that surfaces a significant find — especially for vintage microphone collectors.

THE U60 VS. THE U67

The U60 was born out of necessity when Telefunken discontinued the VF14 tube used in the U47. This forced Neumann’s lead engineer, Dr.-Ing. Gerhart Boré, to reimagine the company’s flagship microphone.

The U60 represents a fascinating transitional phase in Neumann’s design history. While it shares many characteristics with the later U67, there are key differences that set it apart. These early models used a unique large diaphragm capsule design with completely separate front and back plates allowing for true cardioid and figure 8 polar patterns.

One of the most notable differences is the capsule mount. According to vintage microphone experts, the early U60s used a ganged, two-wire strapping as a capsule holder, a design that was eventually replaced by the closed-loop nickel-plated brass ring in the U67. This early ring featured threads for three tiny set screws, holding the capsule in place similarly to how M7 capsules were mounted.

It wasn’t until late 1960 or early 1961 that the final mounting setup was introduced—a design that was used throughout the original U67 production run. This final version used four slot screws to attach the capsule to the mounting ring via threads cut into the backplates, a more robust and reliable solution.

THE LEGACY OF THE NEUMANN U67

While the U60 was a prototype, its successor, the U67, became a cornerstone of modern recording. The U67’s innovative design—featuring a dual-capsule K67, Mylar diaphragm, and EF86 tube—set a new standard for condenser microphones. Its versatility, warmth, and clarity made it a favorite among engineers and artists alike, gracing countless classic recordings.

The U67’s influence extends far beyond its original production run. Its design has been endlessly copied, but never duplicated. Even today, the U67 remains a benchmark for vocal and instrument recording, a testament to Neumann’s commitment to innovation and quality.

Working on a Neumann U60 is a reminder of how far microphone technology has come—and how much of that progress can be traced back to this groundbreaking design. It’s a piece of history, a prototype that paved the way for one of the most iconic microphones ever made.
