Technics SU-7700 Integrated Amplifier Transistor Premain Junk Not Working japan Description Condition: used This is the Stereo Integrated Amplifier SU-7700 released by Technics around 1976. It can be used, but there is a problem with the sound output, so I am listing it as a junk item. ?Appearance: The interior and exterior of the case have been carefully cleaned, so there are no noticeable scratches or stains and it is in good condition. ?Sound output: We connected a record player, FM tuner, CD player, and two cassette decks to the input terminals (phono, tuner, aux) and tape play and rec terminals on the side panel, and checked the sound through the speakers and headphones, and found the following problems.? When the speaker is connected to main, no sound is produced from the right side, so by connecting it to remote, sound can be produced from the left and right.? You wont notice it when listening to music, but you can feel noise when you turn up the volume with no sound (no input).? When the volume is low, the sound on the left side may be interrupted, but this will be resolved over time. ?Operation: The output meter lights up and the needle swings have been confirmed. When switching the meter range (x1, x0.1) to x0.1, the needle swings widely, which is thought to be normal.The power, speakers, high filter, loudness mode, rec mode, tape monitor, input selector, and EQ subsonic switches all function normally.The bass, treble, and balance adjustments all function without any scratching, but the volume is as explained in ?. *The above confirmation method is audiovisual. ?As this is an old product, please be aware that malfunctions may occur due to vibrations during transportation and deterioration over time.
