  6. Wtched this video too late I opened it with a knife which is no easy task and I think I damaged a capacitor

  7. i'm a little confused about that power supply.
    They went to the trouble to use a pwm flyback i.c to drive the primary switching mosfet, then they missed out the opto coupler from the output to the pwm i.c, so the output is not as accurate as it could be.
    Mad manufacturers lol.
    I have seen far worse than that psu, no pwm flyback i.c, just a few transistors as a crude oscillator.
    Very cheap, very crude.
