Not young and cocky, I do look at things differently than a lot of people. I was a kid when I started fixing valve stuff because that's all there was. B+ voltages, just rang a bell. My dad had a vibrator based radio in a 1962 vehicle. I had a Blaupunkt AM/FM/SW radio which the dial was layed out in wavelength in a 1973 vehicle. I was introduced to Sams Photofact as a pre-teen. So, I'm like 10 YO and playing with circuits that generate 600 V or more. I did see the Apollo moon landing live broadcast.
