One thought on “MELZ 6N8S/6SN7 Black Plates holes in plate”
The MELZ 6N8S/6SN7 Black Plates is a sonic time machine that transports the listener straight back to the USSR of the 70s and 80s. These tubes possess an incredibly unique character, defined by a relaxed, mid-range focused presentation. Despite their laid-back nature, they are remarkably “quick”—ranking among the fastest 6SN7 variants I have ever tested.
The soundstage is fantastically wide, and the signature “holes in the plates” design seems to provide a sense of increased air, allowing notes a longer, more natural decay. While many Russian tubes suffer from a brittle or unpleasant treble, the MELZ 6N8S delivers a sweet and detailed high-end that avoids any harshness. With its solid bass and refined detail, this Soviet-era gem comfortably holds its own against “kings of the road” like Tung-Sol, Ken-Rad, and Sylvania. It is HIGHLY RECOMMENDED.
History of the MELZ Factory and Its Special Status
The MELZ factory (Moskovskiy Elektrolampoviy Zavod), located in Moscow, was the crown jewel of Soviet vacuum tube production. Established in the early 20th century, it became the primary research and manufacturing hub for the most sensitive electronic components in the USSR. Unlike other regional factories that focused on mass-market consumer goods, MELZ was tasked with producing high-precision valves for the Soviet military, aerospace programs, and elite scientific research.
MELZ held a unique position because it often functioned as a “pilot” plant where new designs were perfected before being sent to other facilities for mass production. Because of its proximity to the Soviet scientific elite, the factory had access to the highest purity materials and the most skilled labor force in the country. The 6N8S with holes in the plates is a prime example of this superior craftsmanship; the “holes” were a deliberate design choice intended to optimize thermal characteristics and electron flow in high-reliability applications, a feature that audiophiles now prize for its holographic “airy” quality.
Final Verdict
The MELZ 6N8S Black Plates is a top-tier 6SN7 alternative that proves Soviet engineering could reach the same heights as the finest Western manufacturers. It offers a rare combination of speed, sweetness, and a massive soundstage, making it a mandatory audition for anyone seeking a “best-of-both-worlds” performance.
