Multifunctional stereo integrated amplifier with adjustable bass and treble, and multiple input terminals. *Power-on confirmed only* - Brand: Technics - Model: SU-7600 - Type: Stereo Integrated Amplifier - Adjustment Functions: Bass, Treble, Balance - Input Terminals: Tuner, Phono, Aux, Tape 1, Tape 2 - Volume Adjustment: Volume knob - Switches: Loudness, High Filter, Mode, Tape Monitor Operation has only been confirmed by turning on the power. Buttons and knobs are working normally. There appears to be no visible damage, so it seems to be in good condition, but I do not have the environment to fully test it, and I am a novice with this type of equipment, so I would appreciate it if someone with more expertise would take a look. However, as it is an older model, it is unknown whether it is performing to its original specifications. Please be aware that maintenance may be required. Thank you for viewing.
