RE: Oops...time to change that tube

A lot depends on the designer. I know David Berning gives his tubes 10,000 hours and knowing a bit about David that means at least 20,000 hours. His prototype Audionics BA159 was turned on in 1972 and turned off in 1977 with no measurable wear. Then again early Audio Research gear was typically good for 6 months or less depending on usage.
