I’m sorry but you are dealing with this. It’s a major PITA.
I’m the sort that expects when I’ve paid more than the average it better work more than the average.
Things wear out over time, sure, but it still chaps my as* if I don’t get what I perceive as a reasonable life from something. That’s based partly on what I paid, and partly on the construction of the unit, which is adjusted by my experience from years of buying and using equipment.
I’m happy to wear something out, or to find it needs to be re-tubed or re-capped, because, if my choice of the gear was smart enough, it will be years down the road and the repairs will last for a long time.
