Balloon type of
Mesh plate that causes magic to sound
EML 2A3 Mesh is a balloon (glove) type vacuum tube designed with the same standard as the original RCA 2A3. The anode has a special "mesh window" structure, combining the mechanical stability of the solid plate with the soft and natural resonant damping properties of the mesh material. This ideal combination brings out the deep nuances of music.
The change that a mesh anode brings to sound is just magical. The high vibration damping ability of the metal mesh dramatically improves the transparency of the space, and the recorded sound field emerges more realistically and stereoscopically. With a wide sound stage, clarity of localization, and repeatability of air feeling, 2A3 Mesh is one that embodies the full potential of a small output triple tube.

Precise structure and high reliability design
- Gold-plated grid: Improved bias stability and improved linearity of vacuum tube curves. It is also effective in reducing overload resistance and grid current.
- Mesh anode: Naturally attenuate resonance, suppress overtone turbidity, clarify the outline of sound.
- Ultra hard alloy structure: High rigidity materials such as molybdenum and wolfram are used to guarantee long-term stable operation.
- Anti-microphonic design: The suspension structure of filament, grid, and anode minimizes the influence of external vibrations.
- Hand-blown gloves and gold plated pins: crystals of craftsmanship and functionality.
- Black ceramic socket (white bottom):Yamamoto Sound CraftCompatible with sockets.
In addition, vibration-proof rubber is applied to the tube base to thoroughly suppress noise generated by mechanical vibration. V4 version also supports cathode-tapped filament.
Notice of Use
Although the mesh tube has very delicate sound reproduction, spurious noise may occur on the output stage of another preamplifier or in some headphone amplifiers. This phenomenon is not a fault of the vacuum tube itself. EML 2A3 Solid Plate is recommended for such applications.
