When I moved away from home in the early 70's as a young buck I was gifted two identical TV sets, that did not work. One from my Dads Dad and one from my Brothers Father in law. Tube type Zenith's, with remote control's. My plan was to swap out the tubes from one to another. They had safety panels on the back blocking the view to the tubes. I removed the panels, hot wired them on and took my best guess at the tube swap, with limited knowledge. I did know there were capacitors / condensers that held energy that could kick like a mule. Lucked out, and got one working set out of two for free. Took the old set to the land fill and over the bank it went 50 feet away with the tube not breaking but face up. It was too tempting not to throw rocks at, so after plenty misses and one hit but not a big e-nuf rock I hit the target. My first experience with an implosion that sounded like a M-80. The glass did not go outward, like an explosion, but got sucked inward because of the tube being under vacuum.
