Kenwood GE-1100, Tidak Berfungsi

This Kenwood equalizer is not functioning properly, as seen on the 'Spectrum Analyzer' light, which is lit at maximum at 250 Hz, 4 kHz, and 32 kHz... the others show no signs of life. Meanwhile, the 'Reverberation' light is not lit at all 😥, but you can still hear the 'Click' sound of the Relay, which indicates that the current supply transformer is still functioning, but not optimally (seen from the dim LED Graphic light). This video is part one, will be continued in part 2 and the work of dismantling, soldering, and cleaning this unit is not documented, so that the video duration is not too long. Please enjoy and hopefully entertained 🙏
