Go ahead and order a set of tubes. You're going to need them soon, so why wait? This way you'll have them on hand when the old ones start to go and you'll experience no down time. You will know when it's time to make the change, your SQ will change for the worse.
How far over the limit can I go
I am currently just past the recommended 2000 tube life on my power amp. (Audio Research Ref 110). It still sounds glorious. Am I playing with fire here? Or, will I notice some degradation in sound that will prompt the re-tube. I think it's about $1,000 to retube.
Thanks guys!!!
