Ponúkam na preda vintage quadrafónny (štvorkanálový) receiver vyrábaný v rokoch 1973 až 1974. Vo svojej dobe bol považovaný za vlajkovú loď novej generácie vysokokvalitných Sansui receiverov, známy svojím robustným spracovaním a ikonickým dizajnom s dreveným krytom a osvetleným čelným panelom. Zariadenie je vo veľmi peknom dá sa povedať zberateľskom stave, plne funkčné, ktoré prešlo servisnou kontrolou. Drevený kryt má minimálne znaky opotrebenia. Pri serióznom záujme ponúkam možnosť odskúšania. Pre viac info ma prosím kontaktujte v správe.
