UNISON RESEARCH SIMPLY ITALY AMP HI FI VALVOLARE CLASS A pure. preamp and the piloting of the power stage are realized with the use of triode ECC82. These valves allow to obtain a large linearity and the almost total absence of harmonic distortion components of odd order. The first triode amplifier of the input stage is totally devoid of both total and local feedback, to achieve this it is eliminated, the classic drive circuit cathodic polarization of introducing the ionic polarization, the only to ensure the absence of feedback and minimum phase shift of the amplified signals. important note is the ability to select the level of total feedback amplifier allowing a better interface with the speakers, with cables and with the listening environment. The filaments of the preamp valves are fed in direct current to prevent residues of alternating components can be added to the signals to be amplified. stereo2000.it
