There are what appear to be 1976 date codes on some caps.
If its that old then replace all and any electrolytic capacitors plus any
paper based caps.
If they aint bad now they soon will be.

Sorry, this is just a plain dumb answer. If they are good now, they
probably will be good in 10 years, too. We never change any caps just
because of their age.
I suggest: check for electrical safety, then plug it in and try it; after
all, it's "just" a tape reader with a simple PSU, not a 50s era mainframe.
It will just work, I guess. If there should be a problem with those "big
caps", you'll see it. But it's much faster and easier to test them
beforehand (i.e. short or no short) than to foolishly replace everything.
