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?

I have yet to see a preamp tube fail, in contrast I've had a few failures in power tubes (KT120, KT88) that were either silent or resulted in a sudden burst of illumination and no more music...
