Many thanks.
But I am confused:
> the tubes are still subjected to deleterious thermal cycles if the preamp is not left on 24/7
> you may face premature tube failure if you leave the unit powered up 24/7
So, what would be a best practice to save the tube's life time? I listened to music 1~3 hours a day.
I have an int tube amp and will have a tube preamp that will work with a ss power amp. I would not mind replacing to new tubes every 4~5 years, but not 1~2 years.
