Would a relatively short end of wire (i.e. 5cm, in the >sk5b185 case), pointing radially outwards, be acceptable? My coils terminate to 4-40 screw terminals but they are long enough that internal arcing and such are not a problem for the voltages I run. Thus, I just add an additional wire to connect terminals and such. For a fixed wire, I would just wrap it around the secondary just like a few additional turns. A little tape will hold it in place. It is always a little hard since the wire can only be bent so many times before it breaks off! The trick is to make the additional wire "stick out" as little as possible. Neat about letting the wire vibrate and watching the reaction on a scope! > >I finally got all components for building Terry's low-Z >amplifier, and hope to do it within the next days. This will >shurely better my future results. Neat! The amp seems to be working great. Note the added ~600pF cap in the input line to help stabilize the response. The op-amp is a little under compensated but a little added RC filter brings it to a flat response easily. http://hot-streamer.com/TeslaCoils/Misc/Low-ZAmp/Low-ZAmp.jpg Cheers, Terry > >Cheers, > >Kurt Schraner
