Mini Rectifier for Classic Sound
Achieves maximum performance with low current, enriching clear sound field
EML 80 is a rectifying tube that inherits the essence of 5U4G but condenses rich tone and high reliability in a more compact housing. In particular 135mA it demonstrates its true value in the following low-current circuits and increases the sound field expressiveness of the entire system by providing a power supply with very little noise.
The sound produced by this 80 rectifier features a smooth and transparent sound with high impedance characteristics. Compatibility with small-scale systems and headphone amplifiers is also outstanding, drawing even fine sound nuances. Because the power ripple is minimal, the shading of the sound emerging from the silence will feel more realistic.
Even on the structural side, the attention unique to EML shines everywhere.
- Hard metal filament (series connection)
- Hand-blown gloves
- High life with oversized getters
- Gold plated pin & black ceramic UX4 base (white bottom) - Yamamoto Sound CraftFully compatible with sockets

The operating voltage is based on 250V, while the user seeking a more rich representation is designed with a view to using it in 275V. In combination with high-performance chokes such as Lundahl LL1673, power supply noise is almost zero and pure power supply is possible.
EML 80 is not just a compact rectifier. A combination of the elegance of vintage tubes and the precise craftsmanship unique to modern EML. It is recommended for all audio enthusiasts who want to reproduce emotionally from classical to jazz to vocal.
