All electrolytic capacitors have been replaced. Plastic parts have been cleaned with oxygen bleach. The circuit board has been cleaned with anhydrous ethanol. I've done a quick Street Fighter test, and it works without any problems. Sound also works. Console only. Please prepare the cords and controller yourself. The cover is dirty (discolored). Please understand that this is a used item that has been maintained before purchasing. #SuperFamicom #Maintenance #LateModel
