Please be careful.
Kind regards, Col.
Wise advice Colin - I've only had one nasty shock - luckily not from the mains but 500V from a cap reformer that I built. It was connected to a two-gang 13A socket outlet, and instead of pulling the plug out which I invariably do, I'd just switched off. But what had I switched off? The supply to my lathe, connected to the other socket!
I only briefly touched the voltage doubler, and boy did that liven me up. I can recall thinking 'hey - I'm too young to die and too old for nasty shocks'!! It's a lesson once learned that's never forgotten. I was really quite annoyed with myself because right back to my apprenticeship days I was always taught to do as much testing and fault finding by continuity tests with equipment isolated and I do that to this day as a matter of course. Most diagnostic and remedial work on radios can be carried out via continuity and resistance checks and only in the late stages need the mains be connected. I also use an isolating transformer when working on AC/DC radios.
