Otherwise you'll be like the poor technician who returns to an H.V. installation, - from a dentist's appointment, only to find out too late that his colleague has reversed the connections of an inductor/capacitor circuit. Big bang!
Anyone remember the BBC-2 colour test film, circa 1967/8?

Sure do, it was one of my favourites and I always stopped work to watch. Mind you, a LOT of them were worth downing tools to watch.
In the TV trade at that time, it was common to wave a neon screwdriver near the line output stage to check if it was doing something. A pretty crude test, but it showed signs of life.
