I already found a german supplier for copper core wire. It is better because of the shipping. Maybe it will be successfully, but it could be a problem if e.g. the a wrong part is delivered. So I would only order abroad, when I couldn't get it here.
thanks for the kind offer ! It's a small world. But even a little bit to far for short trip in the evening. It is about 200 miles south of here. It's a nice (wine) area there - forest and mountains. I'm living near to the dutch borderline only 125 miles from the north sea cost. Is he a jet pilot ?
