Ken, well done. Do you see where I said "There may be other implications worth considering ". This is the "implications" that I quietly made reference to. I have seen this very subject debated by some pretty big heavy weights. And I use a wall transformer for my equipment. The suggestion you make is a good one, albeit expensive. But life is worth it. Hulda has a couple of suggestions as well. And we can discuss the impact a transformer has on resulting waveshapes. This can be a very in depth discussion as I have seen it on the beck and stuff forum with alvin rose, bob the moderator of microelectricitygerm killer, V and many others. It was a very strong debate and included an electrician. Doesn't matter, you have a good suggestion.
Guess we better start suggesting some of these heavy weight fg, etc equip designers change their transformers. You know whats out there.
