Lifespan of a quality solid state amplifier?


What is the expected lifespan of a quality solid state amplifier (Krell, Mark Levinson, Anthem, Bryton, Pass Labs)? Is their any maintenance that can be performed to extend the lifespan of one of these amps?

Regards,

electrolytic caps have a limited life span.
No way around it.
500k hours I think. Average use 25 years or more. Some caps can last up to 50years. It depends on the environment too.
My 26 year old kenwood sounds like I am listening to a low bitrate mp3.
This is due to electrolytic breakdown.
2 old "low end hifi" SS amps chugging along: 1. a Hitachi receiver SR 2000, circa 1981, 70 W per channel continuous, inherited from my now deceased mother-in-law, has operated without a problem. I use it in my home office. It is on now playing blues..:) 2. my Hafler 9180 purchased in 1995 for $477 has never malfunctioned or shown any sign of sonic degradation.....:)

How would you know if your self described "low end" systems have deteriorated when they don't sound that good in the first place.

You have just put your finger on one of the best things about going sub lo-fi. They never break and if they did, you wouldn't be able to tell the difference. Lo-Fi Rules!!
