TU-05mk2 純粋な真空管ポータブルヘッドフォンアンプ

TU-05mk2 Pure Tube Portable Headphone Amplifier


The TU05 is a portable amp for pure SET (single-ended transformer type) analog headphones with full-stage vacuum tubes that has been a long-seller for over 10 years since its introduction in 2011. In 2021, the internal operating voltage will be increased, the vacuum tube will be able to swing at full swing, power supply efficiency and safety will be improved, and external power input will be supported as standard. (Although it is a simple performance improvement product of TU-05, it is called TU05mk2 because there is no compatibility with the conventional model in terms of power supply and output spec figures)
Enjoy the clear sound of pure vacuum tubes.
