@pindac Thank you for your response. But what is Valve red plating ? I never heard of it.
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.

@simao Ty. I just read it. |
@ghdprentice Thanks for your response. I have to agree now with you. These 750s do have a slow start. And considering the options of leaving them on or off during some of my short listening sessions during the day / night I will now be turning them off. I have about 800 hrs on these KT150s and I also did buy a brand new complete matched set of tubes from ARC when I bought these amps last summer. Also I did already a tube ARC last year when I first got these amps. One of the KT150 tubes must of gotten shaken up during shipping. I think it was the very first time I played them. Scared the FK outta me. I put a post up last year about that. |
@czarivey Thanks for your response. These are my first tube amps I have ever owned. I went from a Krell FPB 600 to the ARC Ref 750s. My first day of owning them I was listening for about 10 min and had a tube arc from a KT150 tube. It sounded like an explosion with a fire and lots of smoke. Scared the FK outta me. I posted this happening on AG last year. |
@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. |
@pindac Thank you for clarity on Red plate. I was just gonna ask how important tube bias is and what can happen if not biased. |
@jetter Read my post from last year about when I first bought my Ref 750s. I had a tube arc from a bad KT150. |
