This is a Roland SC-88 Pro. Released in 1996, the capacitors have all been replaced. Audio-grade capacitors were used instead of standard capacitors. Image 2: Image after replacing surface-mount capacitors on the main board. Image 3: Image after replacing capacitors on the audio board. Images after the replacement are attached for reference. Memory tests have also been completed successfully, and audio output has been confirmed. *Note* One of the screws on the back is missing, but it functions normally. Please refrain from purchasing if this is a concern.
