[Milsurplus] Postmortem on DEF headphone elements

[Hubert Miller]

Ramon Vargas Patron, a university professor in Lima, Peru, a friend of mine, reminded me that these were high impedance elements and to be sure of my measurements.
I rechecked them.
I found ONE with very unusually low resistance. I rechecked the rest and I see I had the tables turned, ONE of eight was defective, not other way around ! Still a higher fail rate than
mil-spec, but not a disaster. I am now puzzled how a low resistance short could occur.
I think my mistake would have been less likely had I been using an old moving - pointer analog VOM.
En ingles, llamamos este un caso de "egg on face".  ( = embarrassment )
This is why we need degreed engineers around: to check our work, keep us honest.
