I've owned my pair for only four years but have had about 20 tube failures. Sorry to say I didn't bother to log these to see if any patterns fell out.
I can say most of my failures take out both the upper and lower tube in a totem pole. I rarely lose one tube at a time.
Also I have never had trouble in both totem poles at the same time. Failures do not cascade from one to the other.
What do you think of this for a format:
Which tube failed in totem the pole? upper/lower/both
What brand(s) of tube?
How did your fusing behave?
Did other parts fail too?
I just ate a pair of Sylvania's last night so I will reply to myself with the first data point ":^)

How did your fusing behave? AC line fuse blew 2.5A FB I2t = 12
Did other parts fail too? no

Jan I've had many many failures and I have not been keeping track of such details until now. No pattern ever presented itself however so I will say random.
One of the things I'm keen to know is does the upper or lower tube fail more? Right now I have no idea.
