As the Commodore Amiga computer age the capacitors will be prone to leaking over time, remember these are 20 plus years old so its a good preventative measure to replace the capacitors as once they leak they will eat through the copper circuitry and cause either permanent damage or an expensive repair job. A capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. Inside a common battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can’t produce new electrons. The most commonly used and produced capacitor out there is the ceramic capacitor. The aluminum electrolytic capacitors, the most popular of the electrolytic family, usually look like little tin cans, with both leads extending from the bottom.
