Tube Life and the Mute Switch


I just got an ARC PH3-SE phono preamp yesterday and for best sound, the manual recommends leaving it on mute all the time when not playing.

The manual says the tubes are good for approximately 2,000 hrs.

How much doees leaving it on mute count against the 2,000 hours? I'm sure it's not the same as playing hours.

Your thoughts please.

All the time on mute will count against the 2000 hours. It seems a strange recommendation given that their website recommends turning off tube gear between uses.

2000 hours is only 83 days.
