The question was in reference to the leached Ac house wiring noise found in all Ac house ground connection, but not found in a proper outside ground. This has nothing to do with Tesla, or what he did, or didn't do.
So, long as people use the AC ground that is located on their test instruments or anywhere throughout the house they will get a dirty ground, with Ac hum or noise , that can especially affect tuning and output test results for these types of circuits.
Minoly, I believe it was, had sent a interesting link of a video of someone showing how that can foul us. As they were brightly lighting an led bulb off of their test instruments AC ground connection. Maybe he would like to upload that link to us again. Just for future reference, as it makes a very important point, for those of us still unaware of that.
So, if anyone is in doubt of where the juice that is lighting their leds is coming from, and if it is or not from the Ac, just turn off the house breakers. This will not affect the workings of a circuit or device when proper outside earth ground connection is used.
BTW: I notice that some guys are using styrofoam type flat sheets or cups to isolate their circuits. Looks like a good idea.
@Slider: I also have several of those type of ferite beads, but no reference yet to their values. There is reference information about them on the internet, but I haven't found the good link to that yet.
Is there a circuit you are using to make your own SEC circuit oscillators?
