This solution has proven to be the best also in listening and audible tests we had carried out. Deviation between sync of left and right channel of attenuator is lower than 0.05dB, this outclasses even the best potentiometers. This accuracy of the attenuator control delivers excellent playback of the recorded soundstage. One of the most important parts of a tube amplifier, an output transformer, has several bifilar windings which are lined up in sections .to maximise power bandwidth.<\/p>
