I got my first shock when I was around 10 years old- I had pulled apart an old radiogram and installed the guts in a redundant cupboard at the top of my wardrobe, with the control knobs poking out of the side. I boxed the speaker into a case and stood it on top of the cupboard. It all worked so I stood on a 3-legged stool and removed the mains wires from the temporary terminal block, then attempted to straighten the wires with my fingers. I came to on the bottom bunk bed (with my brother in it)
I can honestly say that I have reached the age of 59 without another shock, having always had a job that had 'electric' or 'electronic' in the job title- I don't include belts from engine ignition systems.
Six months ago a friend was moaning that her PVR had died, so I suggested that she drop it round for me to have a look at. She appeared with it a week ago so I took it into the workshop, removed the cover and was amazed by the state of nearly all of the electrolytics. I was just about to poke about with my finger and I asked how it could possibly have worked to the point of failure in this state, when I realised that the unit was warm. It turned out that it had been plugged in and ON for the last 6 months ! Everything in her house stays ON all the time, even if it is dead, apparently.
Another lesson learned by Mr BT. I nearly spoiled my unblemished record.
Regards, BT
