Mollycoddling tube amps is silly to me. Although I maybe shouldn’t make a guitar amp analogy in this hallowed audiophile ground (I use tubes for hifi also, but firmly believe nothing is sacred), I’ve owned tube guitar amps that were turned on and off frequently for decades...worked perfectly...same tubes for years and years in some cases. You take your hifi tube amp on airplanes? Blast it on high gain in a club then toss it in your trunk? For years? I don’t drag any of my hifi gear around as...well...nobody does except to audio shows maybe...still...and the answer is turn the damn tube amp off. Tubes warm up in seconds...
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.
