255 v. is less than my stated need.
The production of that -ve. L.V. rail looked like something new to me - at first. But when it's re-drawn in a 'conventional' style, it then appears to be not new at all. Many have been the times I've struggled to understand cct. diagrams drawn 'American style', which, when 'translated', then become understandable.
