Re: [EVGRAY] Bi-torroid transformer Kurt Kokinen 8W out 4Win

Hi Machinatuos and all
 I just watched the 2nd video, with a comparison to a conventional transformer, and there is that annoying high pitch throughout and this he says in the 2nd video is 2.93khz....so went back to the 1st video with the center-tapped primary (there is no center tapped primary in 2nd video) and in the first video that same high pitch is there too, and it sure sounds exactly the same pitch and frequency just listening to the two to compare, so I will assume the frequency going into the BiTT in first video shown 4W in and 8W out is 2.93KHZ also.....however he mentions in 2nd video that it is DC pulsed feed into that transformer (with no center tapped primary), but in 1st video with the 8W out from 4W in, it is again the 2.93khz, but it is now AC because of the center tapped primary and now not DC pulsed....so if you look at frequency being the "entire sinewave" how many times per second, now perhaps it would be 1.45khz you would/could say in AC but regardless, what comes out from the DC pulsed "zero voltage" power source sure seems the same at that 2.93khz pitch and frequency...
