Yet I get the impression that there have been more hams electrocuted over the years by unwittingly putting up antennas that contact overhead power lines than by transmitters!
Peter: You could very well be correct. However, amplifier accidents seldom get news coverage because most people have no idea what an amplifier is. Whereas most know what an antenna is. Since antenna electrocutions involve the power utilities, they get the news coverage.
We had two drunk CB'rs near here buy the farm when their roof mounted (while mounting it) swung over and came in contact with about 18,000V.
I would hazard a guess that many amp owners have no idea of just what they're dealing with when they get to probing around, especially with the incorrect or inferior test gear. (This is why I usually comment when the subjects of amps and meters are posted here)
A good friend of mine who had been a ham for over 50 years just about bought it when he came in contact with 1200VDC in his homebrew amp. At the time he was about 75 years old and in bad health. He was never the same after that when it came to working on his gear.
