How long will tubes last in a pre-amp?

My Sonic frontiers Line One seems fine, tho I haven't put anything else in place of it to test.

It is a decade or more old.  Should I get worried about the tubes?

In my ARC REF 3SE I replaced all the small tubes by 6H30P-DR ,
they should last more than 10.000 hrs.
