Emission Labs EML 2A3M Mesh Plate Matched Pair

The EML2A3-Mesh vacuum tube is designed for the highest sound quality and durability for vacuum tube enthusiasts and audiophiles. Its mesh plate construction dramatically increases sound resolution and transparency, resulting in a rich midrange and warm, natural sound. It is especially excellent in expressing vocals and acoustic instruments, bringing a sense of realism similar to that of live sound sources.

Features and Advantages

Reliability based on RCA specifications
EML 2A3-Mesh is designed in accordance with the original RCA specifications to ensure stable and safe vacuum tube operation. In particular, the grid resistance is properly set to ensure stable performance over a long period of time. This allows the use of historical vacuum tubes even in amplifiers based on EML's high-quality design.

Low Grid Current and High Durability
The grid current when new is less than 1μA, and even used vacuum tubes are inspected to meet the standard of less than 3μA at 250V/60mA based on strict quality standards. This ensures stable sound quality throughout the life of the vacuum tube and reduces the risk of thermal breakdown.

Rich sound field with mesh plate
The mesh plate structure increases the depth of the sound field and reproduces detailed sound nuances compared to conventional plate designs. The breadth and transparency of sound are further emphasized, providing a clear and balanced sound.

Use of high vacuum and high quality materials
EML's vacuum tubes are manufactured using high-purity materials and advanced vacuum technology based on strict manufacturing standards. This ensures stable performance over long periods of use and minimizes degradation of sound quality due to deterioration.

Flexibility in amplifier design
Flexible design is possible by allowing a grid resistance of 1 MΩ for auto bias and 100 kΩ for fixed bias. This broadens the range of amplifier designs using EML 2A3-Mesh, making it suitable for a wide variety of audio systems.

EML 2A3-Mesh demonstrates its capabilities especially in the reproduction of vocals and acoustic instruments, faithfully conveying the subtle nuances and emotions of music. The EML 2A3-Mesh also provides a relaxing music listening experience, even over long periods of time. It is an ideal choice for audiophiles who value the warmth and transparency of vacuum tubes.

With EML 2A3-Mesh tubes, enjoy a true listening experience where the music seems to come alive.

When 2A3-Mesh is not recommended

When mesh tubes are used as output tubes in a separate preamplifier or in a headphone amplifier, spurious noise may occur. This is rare, but when it does occur, it is not a tube problem. Otherwise, EML solid plate tubes are recommended.
