    The fan capacitor you have installed, does it come in polyester film capacitor ie pf? That is, what do I mean to say that the fan capacitor is Pf (Polyester capacitor) only?

    managed to build this with scrap from a computer power supply! really helped us confirm what's going on with our busted tv. Thanks!
    had a pretty good scare with the electrolytic (i had only big 470uF, 400V caps from the PSU) when discharging it lmao
