OP, 😊👍. It is great they have soft start.
Leaving tube amps on.
This is a question I had for a long time. I know it’s not a good idea to leave tube amps on all the time because of tube life and safety reasons. But sometimes I don’t have the opportunity to listen to my system / music for hours at time at one sitting. Sometimes I can only listen to it 45 min - a few hours at a time during the day / night. So my question is would it be better to leave the amps on all day / evening and listen when I can or turn them on / off every time I listen even if is only 45 min at a clip. But to just clarify when I don’t intend to listen that day/ night they will be off. Does turning the amps on / off throughout the day / night do more harm than leaving them on ? Tube life , wear and tear on amps etc. btw I have the Audio Research Ref 750s. Ea amp has 18 KT150 , 6550WE , 6H30.

This isn’t exactly applicable to your question, and what I do might not fit into the structure of your life, but I generally know, on any given day, when I will be listening, and it usually after I eat dinner. So a couple or three hours before I am going to start preparing my food I turn on my CDP and the power supply section of my pre. about an hour later I turn on the rest of my pre (which lights the tubes up) and then after a few minutes or so I turn on the big power caps of my amp and then when I start making dinner I turn on the rest of the amp which lights up the tubes and when I start eating I put on some background music at a real low level. By the time I have finished eating and cleaned up my mess my amp is pretty hot and I tell myself that sound degradation is going to be minimal. (I don’t know if it is minimal, but I tell myself so anyway.) I definitely wouldn’t leave my tube amp on all day or overnight on purpose. Not that it has never happened before. But if you can get it on an hour or so before you start listening, that may make it sound better when you do start listening. |
Leave ARC 750’s on 24 hours a day? 36 power tubes total? I find it inexplicable that anyone would even consider such a foolish thing! No offense intended. ARC power amps are well known to self destruct when even a single power tube blows (ARC doesn't "believe" in fusing tubes). 36 of them? That’s living dangerously.

@bdp24 Who said anything about leaving ARC 750s on 24/7 ? If u are referring to my OP please reread it. |
@immatthewj I generally warm up my equipment about 15 - 20 min. Then I will listen at about 15db for about 15 min before going up to my usual 28db listening level. But to tell ya the truth the amps sound dam good even from a cold start for listening. |
