Is it still functional? If so, I would let it be unless there are actually signs that the capacitors are starting to fail. (Given the age, I would not be surprised). If it is not working properly, it's definitely a good place to start especially if the capacitors are bulging, or shows signs of leak.
If you're looking for someone to actually do this service for you, it's all dependent on where you're located. These are old enough that recapping them would probably not require a huge amount of expertise if you have soldering equipment and some know-how. There are certainly folks around the web who offer this as a service, but you might ask locally to see if there is a repair place close to you.
