Sounds like you've got a challenging and interesting job. As a technician I was always wishing engineers were required to fix equipment for at least two years before being allowed to design it. I'd spend a lot of time waxing eloquent (or something like) on the idea, usually right after I'd spent hours tearing apart some equipment, just to get to the one component that seemed to fail most often. If you are designing something that's not throw away, please keep us poor suffering techs in mind. Anyway, I've probably contributed to more OT drift that I should. Don't worry. If i really wanted to tinker more with electronics, I would. I'm just playing 'the good old days'.
