@echolane, there are some who say that amplifier technology matured as long ago as 1960 - give or take a few subtle tonal variations thereafter.
The only thing of possible concern might be the power rating - but this usually depends upon upon loudspeaker ease of drive.
I used to own a 1970s Japanese amplifier which I gave away about 15 years ago.
As far as I know it's still working fine.
As far as I know it still sounds remarkably similar to a NAD 3020.
