I think there are several grades of old electronics:

- those who only collect without using. They often even refuse to do absolutely anything, no refinishing, no restoration. Display only.
- those who would do minimal repair, like replacing a frayed cord. Will try to repair to a working condition but only to turn on and demo for a minute.
- those who will do full restoration to be able to use daily. There are different shades of them, from a guy who will use yellow caps openly to guys like me who will restuff old caps, to guys like Russ who will do museum quality restoration. What is common between them is that they want to be able to use the sets without them going up in flames.

If applied to stereos, to use it as daily player it has to be the latter. If there is a known flaw that potentially could result in damage, considering price of tubes or replacement transformer today, a proper mod is very desirable. And the "changes to the character" are greatly exaggerated.
