So I have drawn up another simplified circuit diagram, which includes some details not in the "handbook". I can send this out as a .jpg (not brilliant image quality), .doc for MS word '97, or .dxf (Autocad format) file. Let me know which you would like. If someone would like to post it on their web page, please do. I hope there are no errors; please let me know if you spot one, and I will correct it. Cheers, Jim Moritz 73 de M0BMU
