Bakupcpu’s 2 transistor self resonant circuit running a flyback transformer from 140 volts

First time I was ever able to run a flyback transformer on 120 volts. I works pretty good to! It uses ruffly 700 watts. I’m using two 2SC5047 transistors from CRT TVs. If you want to build bakupcpu’s “Self resonant switching power supply low voltage” witch is the circuit I based this on watch his video: https://www.youtube.com/watch?v=oDLVE_t1GuM

Thanks for watching!
