G'day all,
I have a 5v transformer which powers the glo-wire which surrounds the open half of my observatory. The annoying thing is that it "sings" - that high pitch noise you sometimes get from transformers. I've tried a couple and they both have the same tune. Does anyone know if there's a particular type of transformer or something which I can use to avoid having that high pitch noise? It's just a little distracting
Thanks!
