I know about the "protection of knowledge", heck, I am one of those engineers (at least I was) Mind, you I was always against shielding any kind of knowledge. And a circuit like this, isn't anything new or patent protected. The problem is not, that I can't build such a circuit, but it would save me a lot of hard work, just to have some of the parameters. If I had, I wouldn't have to find them out for my self, and I could start improving on the design strait away. thanks for the tip, anyway Cheers Patrick MODEL ENGINEERING DISCUSSION LIST.
