Consider a low frequency transformer used in the auto pilot system of a plane. Now any drift could seriously effect the system accuracy with devastating results.So...
1) Are these transformers required to have a specific burn in beyond reliability testing to ensure that doesn't happen. Where is that specification documented?
2) If said transformer is field replaced from inventory, is there a burn-in cycle required before the system can be released for public flight? Again if this is true, it would be documented by the FAA.
Don't like planes, then substitute another area of precision electronics, medical, nuclear, spacecraft.
Why don't these industries find this same burn-in phenomena the audiophile industry has discovered? Why is this only relevant in audio entertainment equipment and void in other highly precision areas of electronics?
In all my years as an IEEE member I have never read about this issue outside of standard reliability burn-in and well documented component aging, eg, tubes, batteries, and capacitors. Why is that?
