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?

Preamp tubes for the average use listener should last 10 to 20 years
Left a 12ax7 on 24/7 for 10 years and it still tested good
