In general, for a tube amp (or even a tube pre-amp) - if you listened for a few hours in the morning...had a hours-long pause in the middle of the day (say 4 hours)...then planned to listen in the afternoon, would you ever power it down for just those 4 hours, or leave it on?
Question is getting at tube life as it related to wear from being powered on vs. power cycles.
My perception is there is NO instance where I would power up in the morning, power down for 4 hours, then power back up later in the day. It is better for the tubes (forget sound quality, just tube life) to just leave the thing on all day, then flip it off before bed. However, I might be wrong and happy to hear your input.
I also heard different amps are more or less hard on the tubes when starting up - but even if the amp was 'gentle' I'd still thing those heat cycles would put a lot more wear on the tubes.
Don't worry about sound quality for this topic, just curious about maximizing tube life.
Thanks!
