The Technics SU-3150 is an integrated amplifier manufactured by Technics in Japan between 1975 and 1977. This model features a silver finish and offers a power consumption of 190 W at maximum. It measures 386 mm in width, 115 mm in height, and 303 mm in depth, with a weight of 6.1 kg. The amplifier is designed to support various input types, including two phono inputs with a sensitivity of 2 mV and a load impedance of 50 kOhm, a tuner input, AUX, and two tape play inputs, all with 180 mV sensitivity and 40 kOhm impedance. The output capabilities include tape recording outputs and headphone connections as well as support for two pairs of speakers.

In terms of power output, the SU-3150 delivers 17 W per channel at 8 Ohms and 19 W at 4 Ohms, with a dynamic output power of 60 W at 8 Ohms and 80 W at 4 Ohms. It maintains total harmonic distortion at a low 0.5% at 8 Ohms. Frequency response spans from 7 Hz to 90 kHz, with a signal-to-noise ratio of 74 dB for phono input and 82 dB for high-level inputs.

The amplifier includes tone control features with ±11 dB adjustment for bass frequencies at 50 Hz and ±10 dB for treble at 10 kHz. Additional features include a mono/stereo switch, loudness control (+7 dB at 100 Hz), and low/high filters. The SU-3150 was designed with a focus on sound quality, utilizing a differential-amplification OCL circuit and complimentary service configuration to minimize distortion.
