Released in 1984, the Roland Juno-106 is a polyphonic analog synthesizer that has left a lasting impact on electronic music. As the successor to the Juno-60, it introduced expanded preset memory, a full MIDI implementation, and a sound architecture based on a Digitally Controlled Oscillator (DCO), ensuring better tuning stability compared to traditional VCOs. Its iconic stereo chorus and resonant filters give it a warm and distinctive character, making it a favorite in pop, house, techno, and ambient music. Even today, the Juno-106 remains a studio and stage essential.
Over time, certain components of the Juno-106 wear out and require replacement to maintain its performance and original sound. One of the most failure-prone parts is the voice chips (80017A), which often suffer from deteriorating coating, leading to voice dropouts. The chorus module, crucial to the Juno-106’s signature sound, can develop unwanted noise due to aging capacitors. Potentiometers and faders, used for parameter adjustments, can accumulate dust and lose precision. Additionally, switches, buttons, and MIDI/audio connectors may need replacement to prevent malfunctions.
