KORG INC and Noritake Co., Limited Release Vacuum Tube: the Nutube

KORG INC and Noritake Co., Limited are proud to announce the successful development of Nutube, a new miniaturized and high performance tube. In cooperation with Noritake Itron Corporation, KORG INC. has developed the Nutube to offer reliability and efficiency while still generating the same rich harmonics which vacuum tubes are known for.

As with previous vacuum tubes, this newly developed Nutube is structured with an anode, grid, and filament, and operates as a complete triode tube, generating the same rich harmonics that are distinctive of conventional vacuum tubes. By applying technology from Noritake Co., Limited's vacuum fluorescent displays, the structure of the vacuum tube has been modified, dramatically reducing its size and allowing it to consume less power. 

Miniaturization dramatically reduces power consumption, allowing the Nutube to operate using less than 2% of power required by conventional vacuum tubes and making it easy to power the unit on batteries. The Nutube occupies less than 30% of the volume of a conventional vacuum tube. Its small size and low thermal output allows it to be easily mounted directly on a high-density circuit board without using a socket The unique design and state of the art Japanese production facility ensures the Nutubes are built to the highest standard and offer up to 30,000 hours of continuous operating life. The high reliability means that it can be attached directly to the circuit board with confidence knowing that it will not need to be replaced regularly like a 12AX7.
