There are a couple different capacitors. The ones that often need to be changed are electrolytic capacitors. Among other things, they filter out dc voltage coming from the power supply. They are chemical based and wear out kind of like a battery and the amps performance is greatly diminished. The fun with the caps is that they store a charge. Some of them as much as 500v or so even when the amp is unplugged. You have to intentionally/carefully/knowledgeably/safely discharge them or they can discharge to you. Not my cup of tea. Besides it is a lot of un-soldering/re-soldering and I find much soldering to be a tedious pain.
I picked up an old early 70s Marantz 2240, serviced, and a pair of 1980s Klipsch Heresys. Sounds spectacular, tubelike but not quite tube sound. I showed my son how rock is supposed to be listened to, not through earbuds from an iPhone. He is only allowed to go to 5 on the volume knob
