Lifespan of Power amps


What is a reasonable amount of time a power amp should perform without trouble, or need replaced? If kept in good, clean condition I'm guessing 20-25 years, is this correct? I have an 18 year old power amp and am just trying to figure how long it will be until I will need a new one. Does anyone think the technology is the same today as it would have been 18 years ago for amplifiers?

Atmosphere,should I sell my pricey equipment and go back to collecting Martin Acoustic Guitars(lifetime warrantee...."improves with age")? -:)
