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.

Understandable why mute counts against the 2000 hours. Not knowing exactly how my Cary 303 works, I have to ask: if the tubes are only in the output stage of the CDP, does the mute still wear the tubes?
