Korg launches HA-S Nutube Headphone Amp DIY Kit at NAMM 2020

Surprise from Korg at NAMM 2020! With the Korg HA-S Nutube Headphone Amp DIY Kit that brings a variety of special features.

Headphone Amplifier

The Korg HA-S Nutube Headphone Amplifier DIY Kit has a 9-hour run time with two AA batteries but works with a tube. The secret is the very energy-saving, newly developed Nutube 6P1. This works like a conventional tube with anode, grid, and heating, but the heating wire is operated by a DC coupler to save energy.

The assembly of the Korg HA-S is not rocket science and possible without soldering. For this purpose, the DIY kit contains two different OP amps (JRC MUSES01 and JRC NJM4580) and further sound modification instructions for download. Inside there is a switch that controls the negative feedback and thus the sound characteristics. Outside there is a level control for the 10-ohm output (for headphones from 15-ohm impedance), input and output are 3.5mm jack plugs.
