This teardown reminds me of my childhood days. I was about 5 or 6 and I got my first transistor radio. I proceeded to take it apart to see if I could get distant stations in "better." (and I lived in Brooklyn, NY!) I never got the thing to work right after I tinkered with it, and the parents always said that it was the LAST radio they were getting me. However, with each subsequent radio, came the tinkerer in me that would tear it apart, and sometimes get it back together.
It got me interested in electronics, and in Junior High School, I would roam the neighborhood on garbage day, with a friend, looking for old TVs that we could scrounge parts from. Zeniths were our favorites. We built up a great mass of parts, and built all sorts of oscillators, and neat things that made noises, but there were so many parts, that his mother got angry, and told us that unless we made something useful, she was going to throw them all out!
Well, Brooklyn was the home to Eico, a manufacturer of electronics kits. Their warehouse was in an industrial part of the neighborhood, and it was a good place to go dumpster diving on Saturday, when they were closed. I found a schematic to one of their oscilloscopes, and realized that we had most of the parts. We built the thing, only having to go to Canal St., and get a surplus CRT from one of the many surplus dealers at the time. We built the o-scope, and donated it to the Jr. High School, to the awe of our electric shop teacher. (It wasn't much to us, just like reading a map)
That was then, and today, I am a tech for a local government agency, maintaining about 2000 users and their network. PCs were a natural progression to me, and I have done my tinkering there too, but that's another story.
Thanks for this nostalgic teardown, it really brings back quite fond childhood memories for me!
