Rebuild or New?


I’ve been thinking it’s time for a new amp. I have a Carver 200t Magnetic I bought new in 1987. I’ve run the hell out of it. No joke, there has got to be thousands of hours on this thing. It’s never failed me at all. I wonder though, after years of use, could degradation with the electronic parts have slowly, imperceptibly, colored the sound?

A friend told me two things are the enemy of electronics, vibration and heat. So, I have to wonder.

Am not sure but can these things be rebuilt with newer components? Or, should I just get a new amp?

A 20 year old amp is due for at least an electrolytic capacitor replacement. It's like running a car on 20 year old tires. The problem is finding somebody to do it for a reasonable price.
I don't know. In a sense, I would think it is time to do some work on it. But then again, if it works fine and sounds great,it migt not really be necessary.
