The Sanyo DCA-203 is a vintage stereo amplifier that was manufactured in Japan from 1979 to 1982. It is part of a complete audio system that includes the Sanyo FMT-203L tuner and the Sanyo RD-203 tape deck. The integrated amplifier has a solid and precise construction, reflecting the high manufacturing standards of Japanese audio equipment from this era. Its front panel features brushed metal, likely aluminum, finished in a light silver color. The DCA-203 provides powerful amplification with a rating of 2 x 45W at 4 Ohms and 2 x 30W at 8 Ohms, making it suitable for a variety of speaker setups. The amplifier offers a frequency response of 20 Hz to 30,000 Hz with total harmonic distortion at 0.5%. The input sensitivity is 150mV for line inputs and 2.5mV for MM phono inputs. It features multiple input options, including six pairs of RCA jacks for sound sources, along with terminals for one speaker pair and microphone. The amplifier also includes two auxiliary input jacks for headphones and microphones. Despite some original criticisms of its tonal balance, modifications can lead to a much richer audio experience characterized by warm, clear highs and solid bass, reminiscent of late 70s audio components. The overall dimensions of the unit are 42cm x 29.5cm x 13.5cm, and it weighs 5.5 kg.
