One of the basic tenets of how I work is that I will fix it according to the factory drawings, once. If I have to do it again, then it gets my attention and I'm actively looking for whats not right. When the third failure occurs, that piece gets redesigned according to me. I can count the 4th failures on one hand in 60 years of this. Not counting customer PEBKAC of course. The world keeps inventing ever more ingenious idiots... My educational background is almost zilch, I've taught more tech classes than I have attended. An 8th grade education & a G.E.D. My start? I had an alcoholic uncle who, during WW-II, worked as a postal delivery type in downtown Des Moines, and he usually had a radio in the bottom of his mailbag, either going back to a customer after repairs, or given to him to be repaired while he walked his route. I think I was about 8, maybe 9 when I asked him as he was changing the filter capacitor in one of those 'all american 5 tubers', what was actually wrong with the part he was taking out, and he couldn't tell me! He was going by a recipe on the inside of the cupboard door that said to change them if the radio had a hum. So I set out to find out what the part was, and how it could fail. Fortunately, my mother knew where the library was, and one of the things they taught me early on was how to read at 500 or so with good comprehension. The net result was that by the time I was in the 6th grade, I actually had a better physics/electronic education than a high school graduate of the day. Having a health problem that turned out to be a food allergy when we found it several years later, school was both difficult and painful, so when they quit taking my Dr's excuses for my absences, I said to hell with it, and started to do some service work for cig money. By the time I was 16, I was doing the service bench at the zenith wholesaler in Des Moines for all of Iowa and the northern half of Missouri, where I learned just how educational the oscilloscope can be, and I've never been without one since. Being able to watch a circuit do its thing, in real time, is worth 100x what all the math is when its time to see why its not working as planned, although there is a place for the math too at times. What algebra I know, a TI SR-51 calculator taught me. However, I'm not too sure all the dealers at the annual show for the new models in the fall of '51, were convinced this 16 year old behind the podium knew what he was talking about! There were a couple of them that called my bluff and went away chagrined. The rest as they say, is now history, although I quit the cig habit cold turkey about 19 years ago this month, and I've spent the last 44 years as a broadcast engineer, the last 24 as the Chief at WDTV and I'm still doing some of that one or two nights a week as we get ready for digital. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
