Off or On?

@Hmack, let me refer you to this thread in which several of us refer to capacitors drying over time whether in use or not.

Time to service, how to know?

i wonder how we can know for sure that it’s time for service. A lot of members are saying about 10 years for naim components. But it must differ if someone is listening 1 or 2 hours a day or several hours. Personally i have a tube ear yoshino preamp, ear 912. I changed my tubes recently. The preamp has about 10 years, around 4000 or 5000 hours running. I don’t feel any problem. Can i wait some years more? wait that the sound becomes less dynamic or harsch…?

Happy for it to be proved otherwise, I’m continually learning.
