Leave it on?

@spenav 

Have you not heard of the butterfly effect? If not look it up, research it a little. Lots of little things all mount up.

Refrigerators are required to be left on, a fact of life.

The car example was an ironic comparison to make people think. I see it worked on you. It was not like your car engine “doing serious work” It was not meant to be taken seriously.

Manufacturers want you to buy more of the same, it’s called sales marketing and supply and demand. Some manufacturers intentionally build in operational redundancy (like mobile phones), but that’s another subject.

l will ask my stepson about equipment related fires in the UK. He is a chief fire officer Commander for the new Hinckley Point 2 Nuclear Power Station under construction, and the Trident submarines laid up in Plymouth over here in the UK. Will that do? 

It should not be considered a swear word to use stupid, ignorant or the like and l do not address these to any individuals. I’m sorry if you may possibly find my “handle” mylogic in anyway confrontational, but if you do l suggest you are maybe the child here.

My opinions are mine alone and in my opinion only based only on what l believe.

My main system is linked and the components all go to standby mode if not used for about 15 minutes.  If I go away for  a week or more I turn them off.  The 2 old AVRs in my other 2 systems I turn off when not in use since there’s no standby and they heat up and waste much more electricity.  

@larryi  my tubes always seem to last longer when I leave the equipment on 24/7, tube filaments always seem to burn out quicker when I power them on and off daily.

I have a Pass Labs integrated, class AB, and they recommend leaving it on. There's a mute button but it doesn't appear to be a standby.  It still stays warm.

@mylogic Thanks for bringing up the environmental point. One things folks might do if they want to deal with energy costs to the planet is consider voluntary renewable choice programs, such as the ones offered by companies like Xcel Energy. Consumers can support renewable energy generation, thereby reducing their individual carbon footprint associated with electricity consumption without necessarily putting in solar panels, etc.
