Re: Using a variac when testing always wise?
Years ago I was given a 'night scope' which looked as though it was a pretty serious low light detector, possibly ex-military, with an incongruous cheap plastic lens stuck on the end. It was marketed as something to watch wildlife with, but at the time I never thought of using it to look for hot components. I should try to find it, if it is any good for that purpose I could probably use it.
