have uploaded the latest video of the Scalar wave network series. I just released a video on Youtube where I did show efficiencies to a power supply for a driver circuit TC4421a. This video today is the full version including other amplifier technologies. You will learn that the COP greater 1 is not simply achieved. It needs to be fine-tuned. There are various conditions which I will point out in the future to achieve that. You find the video under movies and Tesla coil functions at the end. Login to your registered website before that. Non-members and Basic members can purchase the video.
