Emission LabsEML274 Rectification Tube

Electrically equivalent to the historical vacuum tubes of the original Western Electric EML 274B - a precise sound rectifier

EML 274B is a full wave rectifier that inherits the legendary Western Electric 274 series lineage. Electrically equivalent to the original 274A, the Octal socket enhances compatibility in modern environments. If you need 274A, we will propose EML 80 instead.

The 274B is designed to connect two diode filaments in series, minimizing operation stability and signal impact. It provides stable power when supplying 140 mA of current in a C-L-C filter configuration, especially in combination with small capacitors. This property reduces the mechanical ham from the transformer, minimizes noise radiation, and provides sophisticated sound quality compared to rectifying tubes and semiconductor rectifiers with low impedance such as 5U4G.

The voice of the actual audio enthusiast also highlights the characteristics of EML 274B.

"Since the introduction of the 274B, the transparency and three-dimensional feeling of the music have become even more attractive, especially in small volumes. The noise from the transformer has been surprisingly reduced, allowing us to enjoy cleaner sounds than before. "

"It's expensive, but it's worth it. With the exchange from the 5U4G, the sound changed to a more natural and profound expression. EML 274B is the ideal partner for my amplifier. "

Under low voltage and current conditions, it is flexible to use 20uF capacitors rather than 4uF, and tuning can be enjoyed according to the system.

EML 274B is the best choice that you can confidently recommend to those who stick to sound quality and stability, as well as the high evaluation from audio fans.
