Hello Ron, I see, so actually what you're saying is if they don't work properly straight away, it is better not to use them at all. That's what I am doing right now :-). I'll still give the AC a go with some of them, and then see if the problem will return afterwards. It's quite easy to test it that way, but then I won't need to design a complete test circuit.
