I was wondering if someone could tell me in order from least influence to greatest, what factors would cause tubes to wear out quick? Leaving the amp on too long, pushing it hard, bias too high, etc.? Reason I ask is because I decided to see where my kt66's were on the meter yesterday, and they are ALL just barely on the strong side of "weak" and are not that old. I'm trying to narrow down what I could be doing to wear them out this fast!
Thanks folks!
