This item was stored in a household. It was used with a laptop for approximately the last two years and was working without any problems at the time of listing. When in use, the Input Selector was set to "Tuner," and sound was produced without any issues within that range. I do not have expert knowledge, so other inputs and detailed functions have not been confirmed. Please be aware of this. As shown in the images, there is some rust on the metal parts due to aging. The product surface has been cleaned as much as possible. Please consider purchasing this item as a used product. 【Brand:】Technics 【Model:】SU-8044G 【Type:】Stereo Integrated Amplifier 【Effective Output (both channels driven):】32W+32W (8Ω, 1kHz) 【Total Harmonic Distortion:】0.1% 【Output Bandwidth (both channels driven, 8Ω):】5Hz～40kHz -3dB 【S/N Ratio (IHF-A):】Phono: 80dB, Tuner/Aux/Tape: 97dB, Mic: 70dB 【Phono Maximum Allowable Input:】110mV 【Tone Control:】Bass: ±10dB (50Hz) Treble: ±10dB (20kHz) 【Power Supply:】AC100V, 50Hz/60Hz 【Power Consumption:】64W 【External Dimensions:】Width 430 x Height 142 x Depth 255mm 【Weight:】7.2kg From the following site: https://audio-heritage.jp/TECHNICS/amp/su-8044g.html
