Thanks a lot Al and Raquel for your informative posts. I have and Audio Aero CDP and it is left in standby all the time which means that the two tubes are receiving power 24/7. I also have an 8 year old OTL which has not had power removed from the driver tubes except for power failures. These driver tubes are all original and still going strong. Don
Do you leave CD players with tube outputs on?
I was wondering how many owners of cd players with tube outputs leave their CD players on all the time. I have a Ayon CD-1 with a tube output stage. Based on input I received I've been turning off after listening and let it warm-up at least a half hour before each use. On the other hand, it is my understanding that the electronic circuits for CD players need around 72 hours of being on to reach their full potential. Is there any harm in leaving a CD player with tubes on all the time other than a shortening of tube life?
