THE PERFECT UNION ... Unison Research UNICO 150 + UNICO CD 2 CALL FOR INFORMATION UNIQUE 150 PRE A VALVES OUTPUT STAGE MOSFET DUAL MONO   The circuit heart of Unico 150 is its hybrid structure, with all the gain determined by the first two valve stages, made with triodes configured to present a limited gain and the least possible output impedance. The triode gain stage has its own partial reaction loop, which allows a very low output impedance   The pre-amplification section incorporates solutions that are not less innovative than the final one. It is totally passive and adopts an ALPS armored volume potentiometer with 4 sections.
