David, that is a difficult question to answer as it depends on many parameters from the quality of the capacitors initially installed to the temperatures they were exposed to during their life. Besides, there are different types of capacitors with various dielectric materials. Capacitors also have a "shelf life" so even if there are capacitors that are new old stock but have been laying around for 10 years since they stopped making them... Well, you have to understand that a replacement of that specific capacitor may not be possible so it would have to be replacement of the same value but a different brand.
Does McIntosh even offer a recapping service?
