Since that’s a hybrid amp, I don’t feel you’ll notice the signal tubes degrade as much.
If it was a complete tube amp, with power tubes, you’d notice a big difference when they degrade.
I have an old sansui tube amp. When those 7591 power tubes start to go, you really notice. When you replace them it’s like you have a brand new amp. I’d tube roll your signal tubes because their is quite a difference in the sonic signature of those tubes. It’s also a lot of fun. Glad you’re enjoying your new setup.
