The NuTube 6P1

Korg & Noritake introduce Vacuum Fluorescent Display

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. Production is carried out at the cutting-edge Japanese production facility of Noritake Itron, a subsidiary of Noritake Co.



The NuTube 6P1 is a vacuum tube developed by Korg, a Japanese company known for its musical instruments and audio equipment. Unlike traditional vacuum tubes, which use heated cathodes to emit electrons, the NuTube 6P1 utilizes a triode structure with a miniature fluorescent display panel. This allows it to achieve similar amplification characteristics to conventional vacuum tubes while being much smaller in size and consuming less power.

Here are some key features and characteristics of the NuTube 6P1:

1. **Miniature Design**: The NuTube 6P1 is significantly smaller and lighter than traditional vacuum tubes, making it suitable for compact and portable audio equipment, such as headphone amplifiers, guitar pedals, and audio interfaces.

2. **Low Power Consumption**: Due to its triode structure and fluorescent display technology, the NuTube 6P1 consumes less power than conventional vacuum tubes, making it more energy-efficient and suitable for battery-powered devices.

3. **Tube-Like Sound**: Despite its compact size and modern design, the NuTube 6P1 is designed to replicate the warm and harmonically rich sound characteristic of traditional vacuum tubes. It is often used in audio equipment where tube-like tonality is desired.

4. **Versatile Applications**: The NuTube 6P1 can be used in a wide range of audio applications, including headphone amplifiers, preamplifiers, effects pedals, and audio mixers. It can also be used in hi-fi audio systems and professional recording equipment.

5. **Reliability**: While traditional vacuum tubes are prone to microphonics and mechanical wear over time, the NuTube 6P1 is more durable and reliable due to its solid-state construction. It offers consistent performance and longevity in various audio applications.

Overall, the NuTube 6P1 combines the vintage sound characteristics of traditional vacuum tubes with modern design and technology, making it a popular choice among audio enthusiasts and equipment manufacturers looking for a compact and reliable tube alternative.
