Capacitors, especially electrolytic ones, dry out after 30-40 years. When that happens, they no longer serve their purpose. In the case of filter caps, they help to keep out AC noise from the amp. When they're dried out, they can either burst in your amp (very messy) or take out other components, or can let you get possibly electrocuted.
Filter caps aren't that expensive so it's an easy replacement. If you want, have the amp tech save the old parts in a baggie so that if you sell it, you can include them.
