So other than tubes, capacitors should be the only parts that "wear" out and need replacing (assuming you take good csare of your equipment)?
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?
