content: I bought a nice 560W Kikusui PAD supply on the bay. Of course it weighs about 60 pounds. Of course the fool who sent it, merely gave it 2 wraps of bubbles & threw it into a thin office-style box of printing paper. It arrived seemingly "ok" , but the meter was popped out. Upon removing the cover, I found the MASSIVE transformer had bent the very sturdy frame, when someone threw it all down (I noticed the feet were poking through the paper box).Worse, all the main electronics/heatsinking was completely broken off the fan assembly & just flopping around (sure to make plenty of sparks!). It's supposed to all be held in place by a sturdy bakelite(?) bracket, which was now in a dozen shattered pieces, basically rendering operation impossible. Guess you shouldn't just toss these supplies like footballs. I looked all around for a KIK part number or part for this fan-shaped bracket....no luck finding ANY KIK parts...WHERE are they located/gotten?I finally decided to 3D print my own replacement in ABS....worked great, once I FINALLY found the fan datasheet with the exact hole dimensions (I had been 0.025" off, causing binding).If you need a copy of the file, I can post.You can see some of the broken bracket pieces in one of the photos
