Of course the amps are not electromachanical, but still shows that the lifespan is not easily predictable, only a guess.
My point is that most HDs I see have an 80,000+ MTBF, but there are failures on a regular basis due to one condition or another despite the predicted/average 9+ year life span of continuous use...
It is difficult to predict failure rates here because of all the varying factors. One person's fan mod flows more CFM, others are in a rack dense environment, some are climate/humidity controlled environment, some are on 24 hours a day, some for an hour every other week some are being used to their limits at all time, some never get close.
You simply can't say they will all last for XXX time. It is impossible to tell even without the random elements, let alone the variance in manufacturing, materials, etc.
The MEAN is only an average lifespan, hardly anywhere near accurate for each device. Some will last forever, some only a few hours.
The very term MTBF already is an admission that there is no real accurate predictor, only an average.
I guess what I am saying is that to say you should expect 3 years out of this amp is purely wild speculation at best.
