Thank you for your response, when looking for R11 did you mean where is it used or where can you buy a 50ohm resistor? It seems as if the article and circuit diagram are not as good as I first thought. Should I make it and hope for the best or forget it a try another one. I'm tempted to try it...
Hi, I am trying to build an Octopus Curve Tracer from this circuit diagram (see attached file). I'm usually ok building stuff when I have a circuit diagram, but not good at all in designing circuits. I chose this design as it looks fairly simple and has a defined set of components, BUT the parts...
