About the KA-7100
The Kenwood KA-7100 is a classic integrated amplifier manufactured in Japan between 1977 and 1979. It features a direct-coupled (DC) power amplifier design with a three-stage differential circuit including a dual-gate FET in the first stage, providing highly stable and effective power output. The amplifier delivers 60 watts per channel into 8 ohms and 80 watts into 4 ohms, with a total harmonic distortion of only 0.02%. It offers an extremely wide frequency response from 0 Hz to 100 kHz, ensuring natural and clear sound reproduction with minimal phase and transient distortion. The unit includes tone controls for bass and treble (±7.5 dB), loudness controls, high and subsonic filters, and a mute function. It supports speaker loads from 4 to 16 ohms and has multiple inputs including phono, tuner, aux, and tape, plus tape record outputs. The amplifier weighs 11.5 kg and measures 430 x 149 x 379 mm. Its robust build and vintage design make it highly regarded among audiophiles and collectors.
