In a series of re-engraving of the famous management plan of the US NEW SENSOR Group, of course, it also locked this coveted Mullard name management. After obtaining the same manufacturing process and design as the trademark and the original production line, he moved to St. Petersburg, Russia, and used local high-quality engineering manpower and old OTK technical support to successfully reproduce Mullard EL34, 12AX7, 12AU7, EL84, KT88 and other series of classic tubes .
All new re-engraved versions adhere to the original requirements to show the characteristics of the old tube. The vacuum treatment and internal metal materials, as well as the material and thickness of the glass bottle body, and even the pin solder ratio, are implemented in accordance with the original tube's technical manual. The new century factory management and more stringent testing also make the re-enacted version more reliable and complete. Even the packaging is completely executed in accordance with the existing printing, and the texture is very good.
