I am reading online for expected tube life of 45 tubes when run at spec and conservatively (where I can find anything because searching for 45 turns up all sorts of hits even when modified with various other tube related words). I find anything ranging from 1,000 hours to 3,000-5,000 up to 10,000. Anyone either know manufacturer suggested life or personal experience? Just curious, one of those things I like to know for tube I run when I can find the info. Thanks!
