***We suggest our preamps are left on 24/7/365 as the tubes and all parts will last longer that way.
Well, the jury left long time ago, and it is still out on that one. That is certainly one common opinion, but strictly speaking, not based in any reality.
If I use my equipment for one hour every year... should I still keep it on?
What if I use it once a month?
Once a week?
Tubes DO wear out when running, there is no way around that. It is also pretty safe to presume that today the great majority of tubes get replaced not due to hard failure but wear out. Therefore one might conclude the thermal cycling is definitely not the main killing mechanism responsible for tube degradation.
Furthermore, constant elevated temperature will - without any doubt - accelerate the drying out of electrolytic capacitors.
Life of many electronic components is rated in hours... and for good reason. There are over 8000 of them hours in a year.
One should also not consider all thermal cycling equal. It can be made more or less severe.
As often is the case in life, there is no simple answer.
