A new vacuum tube which puts vacuum fluorescent display technology to practical use


Nutube, similar to a conventional vacuum tube, has an anode grid filament structure, and operates exactly as a triode vacuum tube. Also similar to a vacuum tube, it creates the same characteristic rich overtones. By applying their vacuum fluorescent display technology, Noritake Itron Corp., a Noritake Co. Ltd affiliated company, have devised a structure which achieves substantial power saving, miniaturization, and quality improvements when compared with a conventional vacuum tube.

Realising substantial power savings

By making the form smaller we have succeeded in making significant power savings requiring less than 2% of the electrical power of a conventional tube. This allows for efficient and simple battery operation.

Small size

Nutube is less than 30% of the size of a conventional vacuum tube.

Real vacuum tube sound

The real triode structure produces a warm, unique vacuum tube sound, delivering excellent linearity.

High reliability, long life

Made in Japan. 30,000 hours of continuous life expectancy
