You probably need to leave it alone !!!
Best procedure would be some test equipment to check each cap in the
circuit. ( There were ESR meters, for in-circuit testing, two decades ago, likely still today, maybe improved models ). ONLY then, can you know, really know, if there are any needing replacing.
If you replace caps, the amp's sound will likely change, not necessarily for the better.
We have worked extensively with certain solid state receivers, from 1976 ( 39 years old ). In some instances, ALL the caps we pulled out to replace - tested like NEW. In some instances, when we willy-nilly replaced a stock cap with a new one, the "magic" of the piece went TOTALLY away.
So, I would think any quality cap, not run at the edge, would be good for 2 to 3 decades, easily.
Of course, if the amp wasn't built well to start with, that is a whole other can of worms !!!
