Replace those which are close to their end of life and/or defective.

There is no rule such as "replace part X or Y". Every vintage gear has its individual history, was stored and operated differently. Therefore, aging of certain parts is different, must be judged case by case.

If you post close-up photographs of the boards, advice is possible.
