1) It took a bit of memory to recall, some via notes taken at the time, just what I had done when I constructed the pannel 3..maybe 4..years ago! anyway, checking the A?C and memory was mostly correct. So onto paper it went. This is version 1, I think.
2) this may be the final version that was printed for the operators manual.
3) This turned out better than I expected, and it too is included in the ops manual.
