Emission Lab EML 2A3M Mesh Plate Matched Pair

The EML2A3-Mesh tube is designed for tube enthusiasts and audiophiles alike with the highest level of sound quality and durability. Its mesh plate construction dramatically increases the resolution and clarity of the sound, resulting in a rich midrange and a warm, natural sound. In particular, it excels in the expression of vocals and acoustic instruments, bringing a sense of realism like a live sound source.

Features & Advantages

Reliability based on RCA specifications
The EML 2A3-Mesh is designed according to the original RCA specifications to ensure the operational stability and safety of the vacuum tubes. In particular, the grid resistance value is set appropriately, so that stable performance is maintained over a long period of time. This allows amplifiers based on EML's high-quality design to use historic vacuum tubes.

Low grid current and high durability
The grid current is less than 1 μA when new, and even used vacuum tubes are tested to meet the standard of less than 3 μA at 250 V/60 mA according to strict quality standards. As a result, stable sound quality can be expected throughout the life of the vacuum tube, reducing the risk of thermal damage.

Rich sound field due to mesh plates
The mesh plate structure increases the depth of the sound field compared to conventional plate designs, reproducing fine sonic nuances. The breadth and clarity of the sound are further emphasized, providing a clear and balanced sound.

High vacuum and high-quality materials
EML's vacuum tubes are manufactured according to strict manufacturing standards, using high-purity materials and advanced vacuum technology. This ensures stable performance even during long-term use and minimizes sound quality degradation due to degradation.

Amplifier Design Flexibility
It allows a grid resistance of 1 MΩ for autobias and 100 kΩ for fixed bias, allowing for design flexibility. This expands the range of amplifier designs using EML 2A3-Mesh to accommodate a wide variety of audio systems.

EML 2A3-Mesh is particularly effective in the reproduction of vocals and acoustic instruments, faithfully conveying the subtle nuances and emotions of the music. In addition, even if you listen for a long time, you will not get tired of listening, and you can listen to music in a relaxed way. It's a great choice for audiophiles who value the warmth and clarity of vacuum tubes.

With EML 2A3-Mesh vacuum tubes, enjoy a true listening experience where music is alive.

When is 2A3-Mesh deprecated?

If a mesh tube is used as an output tube for a separate preamplifier or used in a headphone amplifier, spurious noise may occur. This is rare, but if it does occur, it is not a vacuum tube problem. Otherwise, we recommend EML Solid Plate Tube.
