What makes you so sure, that this is the problem? Is that a common problem or is that likely the problem due to the description? Although I don't have a degree in electrical engineering, I do fix my model railroads myself, so I think I can solder in a new capacitor. However, I'd like to know for sure that this is the problem. How can I test it before I spend money on something I don't need. And what are the specs of this capacitor?
