Life of KT150 tubes on ARC Amps

I have Audio Research 250SE amps and the tubes in it have 2400 Hours. I wanted to hear experience from other ARC users if they replaced KT150 tubes before 3000 Hours.  I am not sure if i need to replace them now or wait for some more time.   I dont have new set of tubes for me to compare with my current tubes and wanted to hear from other people who replaced the tubes.

I would be surprised if the KT-150s are worn out after 2400 hours. 3000 to 4000 hours may be a better point to pull and test.

If you are that concerned why not get them tested. I use KT-150s on a daily basis and have periodically tested them. Quite a ways from wear out.
