Lotton X-5 Single-Ended Ultra-Linear Tube Amplifier: A Modern Interpretation of the Classic EL34

The EL34 pentode tube was introduced in 1949, designed by the British company Mullard. Its applications have been extensive, ranging from radios, electric guitar amplifiers, and home audio systems to military equipment.

The EL34 not only witnessed the rise and fall of the vacuum tube era and became a legend in the audio world, but it also embodies the golden age of post-war industrial design. It is more than just a circuit component—it is a vessel of European craftsmanship, musical aesthetics, and the cultural history of audio development.

Lotton Electronics, considering the listening needs of stereo enthusiasts—including aesthetics, price, sound quality, and space—has launched the K4 full-range speaker unit, a no-compromise bookshelf speaker perfectly matched with our own tube amplifiers.
