I'm assuming you meant you haven't yet changed out any caps or electrolytics. They don't "leak" physically, but they do leak electrically due to age, especially electrolytics. The dielectric (insulator) dries out over time and renders the capacitor useless. Replace them all, paper and electrolytic. Resistors may also be a problem, but start with the capacitors.
