Assuming you can trust the labeling, those power supplies are by OSRAM, according to the board labeling. And that's pretty much an A-grade lighting manufacturer. I suspect these are not supposed to be used as bare boards in plastic enclosures, and/or they're supposed to be used with forced air, and/or they're fake as a whole, and/or they got stuck with a bunch of fake parts.

Great videos. I made an either/and counter on minecraft with my 7 year old nephew. He liked it didn't fully get it but liked it, he is getting older I was wondering if there are any other electronic chips that are basic that I could go over with him to help us both understand these videos better. Everyone liked to break things down when we were younger but rarely do we learn much from it, these are great. It nice how you break things down to the smallest scales, knowing everything. Anyone can give suggestions for chips/circuits to make on minecraft, nephew is smart and I'm trying to encourage it to it's fullest.

Why would a 60V *input* need three caps in series, and so much separation between the tracks, hmm? :) If anything, that looks to me more like something resembling a CCFL inverter, with those freestading FETs making up a full-bridge driving that "quad-bobbin" output transformer.

The "Cylopedia" is similar to a set of old :Hawkins Electrical Guide" books my Grandfather had. I borrowed two of them, but never returned them. My Uncle sold or threw them away without mentioning them to me, so I couldn't add the two missing ones to the collection. I still have the two volumes. A complete set in poor condition goes pretty good money on E-bay. I never found a cheap set missing the volumes I have, however.
