I'd say that a general rule is - If it isn't broken, don't repair it.

Can you somewhere spot some obvious faults like hum, noise, scratches when turning a ob here or there? If you can, concentrate on fixing this.

If the amp is old and have been running under bad (hot) conditions the PSU caps may have dried out a little and let through some ripple. Else I cannot see that any swapping of good standard components to (overrated and overpriced) HiFi components will do much difference, maybe even on the contrary ruin something.

Much of the quality (HiFi or HiEnd) is depending on the construction of the amplifying ciruitry. Choice of components are just ppm (parts per million) when it comes to tonal qualities.
