Ive made hundreds. Few off the top of my head
- Accidentally sticking an EL84 into the EZ81 socket of a radiogram chassis. Funnily enough there was HT just a little low. Once the EL84 warmed up there were some fireworks. Still worked as an output valve though
- Destroyed a Germanium transistor in a jukebox through clumsy application of a scope probe
- Tripped my RCD working on a live chassis radio by touching an earthed soldering iron pin to the chassis. Then falling over finding my way to the house in the dark to flip the RCD back on
. This has actually happened so many times now I always use an isolation transformer with live chassis radios. I'm pretty good at cutting power, not so good at removing the plug from the socket!
