audite84 is right. Electrolytic caps decay over time. Even if the units are working, it's unlikely that they are at peak performance. A 535 is a very good amp, and well worth having this done. If you have been happy with the performance, it's probably more economical than buying new.
Lifespan of amps and preamps?
Hello. I have been listening to the same NAD 1240, Adcom GFA 535, and B&W dm 620s since I was 20 in 1990 (it was a big deal to buy all that as a 20 year old kid...). Other than doing a thorough cleaning on the adcom a few years back when it stopped working, I have literally done nothing to these components.
Are they totally dated, meaning past their intended lifespan from an internal component perspective? I have to say it all still sounds really good to me. But I never really listen to other systems.
Thank you for any input!
