The United UT Tube67 is a large diaphragm condenser microphone that combines a custom UT K67 dual backplate capsule, a hand-selected NOS EF86 vacuum tube, and a custom-wound UT transformer to deliver a silky, full-bodied sound with exceptional versatility.

Design and Build

The UT Tube67 features a solid milled brass body finished in nickel electroplate and black satin paint for durability and premium aesthetics. The 34mm brass capsule, skinned in a clean-room environment and 24k gold-sputtered on 6-micron Mylar, is tuned to the original 1960s specification, ensuring faithful sonic reproduction without the harsh resonances often found in modern replicas.

Sound and Performance

Its NOS EF86 pentode vacuum tube imparts a velvety, creamy character, delivering warmth and intimacy particularly suited to vocals. The microphone offers a linear frequency response from 20Hz to 20kHz across three polar patterns: cardioid, omni, and figure-of-eight. With a sensitivity of -38dB, a maximum SPL of 137dB at 0.5% THD, and self-noise under 11dB, it provides clarity and headroom for both delicate and high-pressure sources.

Versatility

Engineered for a broad range of applications, the UT Tube67 excels on strings, brass, woodwinds, pianos, acoustic and electric guitars, and percussion. Its transformer, custom-wound in the USA, ensures accurate low-frequency response and rich harmonic detail. Additional control options include an 80Hz high-pass filter for reducing low-frequency rumble and a -10dB pad for handling loud sources.
