Don Smith Device Project Part 35: Resonant 60hz Transformer Experiment :)

High freq driver temporarily down, so i wanted to try something that most people could do with a regular high voltage NST running on 60hz. So i , measured 121mH on the NST primary, and added 60uF (supposed to be 58uF) and observed a dramatic drop in input current, without dimming the light at full brightness. Then on the Primary tank circuit i added another 10nF for a total of 20nF on the 928uH L1, it seemed to work best for whatever reason. Output not measured but im overvolting the bulb due to the rate of bulbs im going thru lol Not as good as the high freq driver, but here Input was 49vac and current dropped from 1.1amps to .35amps, and im sure the peak to average power ratio means the input power can be even less than the typical straight DC calculation of Volts x Amps 🙂
