From the Manufacturer
Vacuum tube sound anywhere
HA-S is a DIY (self-made) kit with Nutube for high quality sound quality.
No soldering required, even beginners can assemble and enjoy your favorite music with high sound quality.
Make a headphone amplifier with your own hands
The HA-S DIY kit requires no soldering and makes it easy and fun to create headphone amplifiers.
Whats more, this amplifier delivers authentic vacuum tube sound that audio enthusiasts love to have.
Equipped with Nutube
Nutube is a fully analog next-generation vacuum tube developed in collaboration with KORG and Noritake electronics.
Nutube is composed of anodes, grids, and filaments as well as traditional vacuum tubes, and works as a complete triple pole tube.
It provides the rich, weighing characteristics of vacuum tubes in a smaller, more stable and energy-efficient way. Light and small, Nutube light see through case design, HA-S is the perfect choice for carrying high quality audio
Energy-saving
The DC-DC converter provides efficient conversion when generating the filament power from the battery.
This reduces current consumption and improves battery life.But there is no compromise on the sound.
The HA-S produces 26V line voltage with only 2 AA batteries to drive Nutube for rich, authentic vacuum tube sound!
Tone Possibilities
The HA-S is equipped with an NFB (Negative Return) switch.With this switch, you can switch between clean and clear sound with high quality sound and warm double sound like vacuum tubes. When the negative return switch is off, it becomes a circuit without return, and it will increase the multimodes of the Nutube (tri-pole tube) to produce a rich, more vacuum tube color.Turn on the NFB switch to reduce distortion rate and double noise, resulting in a more "high-fidely" sound.
2 types of optics are included
Comes with 2 output amplifiers to change sound.JRCs premium audio-oriented "MUSES01" and "NJM4580" are known for its classic form.They can be easily replaced with an IC socket. Also includes circuit diagram for customization.By changing parts to a higher quality sound component, you can easily create your own headphone amplifier to match the tone and performance you want.
