Like the classic analog component, the Nutube is structured with an anode, grid, and filament.It's purported to generating the same rich harmonics as conventional vacuum tubes. But there are three substantial advantages to Nutube.
- Low power Consumption – less than 2% of the power used by conventional vacuum tube
- Size - It's under 30% of the size of a conventional vacuum tube
- Reliability – This model offer up to 30,000 hours of continuous operating life
The project is a product of a partnership between Korg and Noritake. But It was Noritake's background in vacuum fluorescent displays on which this design is based. The Nutube appears to be (basically) a two-segment VFD (Vacuum Fluorescent Display .)That old tube comprised of anode, grid, and filament is very similar to a VFD composed of a monofilament cathode, grid, and anode. But because of that base design I have doubts that it provides much amplification. So it may be more for color, so to speak.
