Sure seems that way to me sometimes.

Though on the other hand,  there are a number of kinds of equipment that seem 
to stress the tubes pretty hard and wear them out quicker (the Marshalls I 
mentioned being a prime example) and other stuff that doesn't,  which I think 
also has a lot to do with it.

Going back oh,  20 years more or less I was quite comfortable working on tube 
gear.  These days I don't know that I would be,  based on what I hear about 
the quality of the tubes out there.
