Tubed Pre Dying? ?

I've noticed that there is now some (faint) noise coming through my system where there was none before. Could this be a signal that my CJ tubed PV14L may be in need of new tubes? I bought it here, used, but the tubes shouldn't be more than 1.5 years old.

What are the signs of dying tubes?

Thanks for any suggestions.

My friend has a PV14L, nice preamp. He is sending his to the factory for a mk II version upgrade, which I believe includes re-tubing. It is only costing him about $275 + shipping. There are other cap/resistor/? upgrades as well. This may be something for you to look into.

John
