Assuming both your eyes are nearly the same, get a pair of powerful ready
made reading specs from Boots etc just for this sort of thing. Much more
useful than a magnifying glass. I've found +5 added your normal distance
prescription about right.

But what are you expecting to see?

While big power components have the potential to go out spectacularly,
those carrying signals are much better at dying in a more discrete
manner
