Kenwood KA-5002

 Kenwood KA-5002 (1971) is Direct coupling Stereo amplifier  and offering less power than some other stereo amplifiers, the 150 watt (IHF) KA-5002 also manages to achieve a true audio eminence in the presentation of pure sound. Superb frequency response and ultra-wide bandwidth with lowest-possible IM distortion are achieved through the KA-5002's all stages direct coupling circuitry and pure complementary-symmetry driver stage. All the other thousand-an-one Kenwood quality extras are included to make this an ideal stereo system.
