This 100W+100W (4Ω) output stereo audio power amp operates at AC100V. 2 Nutubes are used on the left and right channels making use of Nutube’s linearity, producing no feedback and adding a moderate overtone to musical compositions.
The power amplifier utilizes the well-established ICEpower 125ASX class D amp unit.
With the vacuum tube amp, which makes use of an output transformer, peculiarities in frequency characteristics are produced through the interaction between the transformer and speakers, often said to be an important aspect of the tone of a vacuum tube amp. As output characteristics of vacuum tube amps which utilize output transformers are also reproduced, an even more vacuum tube amp-like tone is realized through adding speaker feedback. The Nutube Audio amp is also extremely light at approx. 2.3kg.
