I would expect 5000 hours. You need to get them tested. The rectifier will last even longer.
Blame the sound on the power cord. They do need break in time.

Cary SLP 05 - When To Replace Tubes?
Hi
I have a Cary SLP 05 preamp. recently, I changed some power cords on source components and added a USB and SPDIF reclocker. The overall result was the bass became resonant and boomy, so much so that my ears ring after prolonged listening. It could be a power cord mismatch but i have a feeling power cords do not alter the sound that much.
I suspect it may be the tubes getting old. I use NOS RCA Grey Glass GT’s for the quad and Sylvania GT’s in the balanced positions. They are about 5 years old with playback time of 5 hours every weekend (estimated 1,250 hours of use) and measured in the mid to high 90’s when I purchased them. I do not have a tube tester.
Does anyone know what the lifespan for these tubes are and if it’s time for a replacement set? I am guessing if it is time’s up, I’ll need to replace all 6.
