Oktava ML11m (1960s)
Restored Soviet unidirectional ribbon microphone with upgraded hand-wound toroidal transformer
This Oktava ML11m has been fully serviced and upgraded with a custom Russian hand-wound toroidal output transformer, providing greater output and improved tonal balance while preserving the original character of the design. It has also undergone a complete mechanical and acoustic restoration, including cleaning of the ribbon motor and acoustic chambers, disabling of the band-limiting choke, and installation of a new precision ribbon. All restoration work was performed by Cole Suddarth at Cole Picks Vintage.
The ML11m was Oktava’s flagship unidirectional ribbon microphone and is likely the rarest model they produced. Built in the 1960s, it was designed as the cardioid counterpart to the Oktava ML15 figure-8 ribbon microphone. Once serviced and optimized, the ML11m becomes one of the most musical ribbon microphones we’ve heard, combining fidelity, weight, and personality in a way that makes it exceptional on nearly any source including drum overheads, vocals, guitar amps, or room ambience. It also performs beautifully as the mid mic in an M/S stereo configuration with the ML15 and has become one of our favorite kit mics, positioned directly above the batter side of the kick drum, equidistant from the snare and toms.
When we first tested an ML11m, it sounded thin and underwhelming until we discovered a common issue with this design: the acoustic chamber behind the ribbon often becomes clogged with hardened adhesive and deteriorated cloth after decades of use. Cleaning and restoring this chamber completely transforms the mic’s sound, revealing its full bandwidth and tonal complexity.
The ML11m’s original circuit also includes a choke and LC network that limit its frequency response, likely for broadcast use. Disabling this network, combined with the upgraded transformer, dramatically improves the mic’s extension on both ends of the spectrum while maintaining its classic ribbon tone with impressive midrange and top-end clarity for a microphone of this era.
This example is in very good cosmetic condition and is fully functional. The Oktava ML11m stands as one of the most distinctive and sonically rewarding Soviet ribbon microphones ever produced, especially in this upgraded and restored configuration.
