AKAI AMPLIFIER AA-5500. Japan 1973. In magnificent aesthetic and functional condition. Silver-plated with wooden sides. Fantastic sound. Solid State Stereo Pre-Main Amplifier This dynamic 120 W music power stereo pre-main amplifier is ahead of its time with highly advanced circuitry, multiple amplifier convertibility, versatility, and design. SEPP-ITL-OTL circuit and power bandwidth of 20to 45 Hz for full dynamic range and the realization of less than 0,1% distortion. The direct-coupled preamplifier and phono amplifier circuits utilize spece-age integrated circuits for superb tone quality. The playback and recording jacks can be used separately or simultaneously for varied recording and playback techniques. Multiple input, output and speaker connections. The pre and the main amplifiers can b separated for future multiple amplifier operation. Attractive design to blend in with any audio components.
