DIY U87 as Good as Original: Unleashing the Power of Home-Built Microphones

Hey there, music enthusiasts and DIY specialists. If you’re on a quest to create a legendary microphone like the U87 on your own, this article is perfect for you. We’ll explore how to achieve a DIY U87 as good as the original by using top-notch components, clever design tweaks, and some elbow grease.

The U87 Legacy

Before we jump into the DIY part, let’s talk about the iconic Neumann U87. Released in the 1960s, the U87 has become an industry standard for recording vocals and instruments. Its warmth, clarity, and versatility have captured the hearts of artists, producers, and engineers worldwide.

Understanding the U87’s Key Components

To build a DIY U87 as good as the original, we need to identify the microphone’s critical components. Here are the main ones:

Capsule: The U87’s heart is its K67 or K87 capsule, known for its detailed and smooth sound. We can either purchase an original capsule or build one from scratch.
Amplifier: The U87’s amplifier is a custom-designed circuit that provides a clean and gain-stable signal. We can use a similar design or opt for modern alternatives.
Power Supply: The power supply is crucial for maintaining the amplifier’s performance and preventing noise. We’ll need to create a reliable and low-noise power supply.

Purchasing or Building a K67/K87 Capsule

The capsule is the U87’s most crucial component. If you’re looking for an authentic sound, purchasing an original K67 or K87 capsule is the best option. However, this can be expensive, with prices ranging from $500 to $1,000.

A more affordable alternative is building a K67/K87 capsule from scratch. You can use specialized mic-making supplies or repurpose existing components.

Designing the Amplifier Circuit

The U87’s amplifier is a key contributor to its signature sound. To replicate this, we can use the following alternatives:

Original U87 Schematic: Use the original U87 schematic as a starting point. However, this may require some tweaks to accommodate modern components and ICs.
EF86 Circuit: The EF86 circuit is a versatile and easy-to-build alternative. This design provides a similar gain structure and sound quality to the original U87.
Modern IC-Based Amplifiers: A more modern approach is to use IC-based amplifiers like the NE5534 or the THAT 1510.

Creating a Low-Noise Power Supply

Split-Rail Design: A split-rail design is ideal for a low-noise power supply. This approach uses separate positive and negative voltage supplies.
Linear vs. Switch-Mode Power Supplies: Linear power supplies are quieter and more suitable for high-end applications. However, switch-mode power supplies can also work well if designed correctly.

Additional Tips for a DIY U87 as Good as the Original

Here are some additional tips to consider when building a DIY U87 as good as the original:

Chassis and Mechanical Assembly: Use high-quality materials and precise manufacturing techniques to build a sturdy and durable chassis.
Components Selection: Carefully select components that match the original U87’s specifications or performance. Avoid using inferior or low-cost components.
Cable Management and Shielding: Use proper cable management techniques and shield cables to prevent electromagnetic interference and hum.
