The Technics SU-7600 is an integrated amplifier produced between 1975 and 1977 in Japan. It features a black chassis and does not come with remote control functionality. Designed with a focus on performance, the SU-7600 offers a continuous power output of 41 watts per channel at 8 ohms, and 50 watts per channel at 4 ohms, making it suitable for a range of speakers. It employs a fully discrete power amplifier circuit with a direct-coupled differential amplification setup, which contributes to its low distortion ratings, hovering around 0.2%. The frequency response ranges from 7 Hz to 75 kHz, allowing it to reproduce a wide spectrum of audio frequencies with a minimal variance of ±0.3 dB.
In terms of connectivity, the amplifier includes two phono inputs, a tuner input, an auxiliary input, and two tape inputs, along with output options for tape monitoring and two sets of speakers. Additionally, it has a headphone output featuring a 6.3mm jack. The device incorporates tone control features for both bass and treble, adjustable by ±12 dB, and employs a loudness switch beneficial for low-volume listening. The amplifier also includes high filter functionality to eliminate high-frequency noise. Key specifications include a damping factor of 50 at 8 ohms, a signal-to-noise ratio of 60 dB for phono inputs, and a robust power supply with a high-voltage electric field capacitor. The SU-7600 was sold separately with an option for a wooden case. Overall, the Technics SU-7600 is a versatile and durable amplifier, reflecting the high standards of Japanese audio engineering during its time.
