Built-in Nutube

Nutube is a new and revolutionary all-analog tube sound , developed by KORG INC. and Noritake Itron Corporation. Just like a regular vacuum tube The Nutube consists of an anode, grid and filament and operates as a complete triode tube efficiently generating response and the same rich harmonic characteristics like conventional vacuum tubes, but in a more compact stable and energy-efficient housing. way.

The transparent body of the HA-S allows you to peek into this technology; allows you to constantly see the glow of the tube.

Energy efficiency

The Nutube filament is powered by a DC/DC converter , which consumes less electrical current and therefore Provides longer battery life than other tube amplifiers. The design is so efficient that HA-S can control Nutube with 26 V mains voltage using only two A4 batteries for rich, authentic tube sound.

Audio Capabilities

When the NFB switch is in the OFF position , the harmonics present in the Nutube (triode tube) will be amplified creating a sound rich in harmonics warmth and texture. When the NFB switch is turned on distortion factor and frequency characteristics will be changed creating truly detailed and clear sound. HA-S has a special NFB (negative feedback) switch which allows you clear sound, oh...
