All, Potentially useful info for the list: 1) Stylewriter power supply uses zero-screws (or whatever you call them). 2) Stylewriter PS has a seperate fuse in the - leg of the output, and it's easy to desolder. The long version: Sat down with murder in my eye to work on the power supply. Pete Turnbull wrote (on another thread) A perfect description of the three fasteners holding the case together - as I realized once I had them out in the light of day. Unfortunately I *got* them out in the light of day by trying to pop them loose after heating with a soldering iron. Instead of melting the studs the threads were threaded into, I melted the barrels of the recesses the screw heads were in. Things Got Smelly, the case creaked apart, and the recess barrels were left with the studs, screws still firmly in place. However, at that point, I was able to grab the severed barrels, squeeze with pliers until the walls of the barrel gripped the zero-screw head, and twist out the zero-screw. Anybody need 3 slightly used zero-screws? *I* sure as heck don't! To put back together, I plan to find longer pan-head screws with similar diameter and thread pitch, put around the studs plastic soda straws long enough to reach up to the other side of the case, then put the pan-head screws (with washers as needed) through the holes that originally formed the tops of the recessions and through the straws into the studs. (The soda straws are to electrically isolate the screws from whatever voltages are flying around inside, because the recess barrels ain't gonna do it, now being in pieces in my trash can (with extreme prejudice).) Inside, there's a big transformer. One side has 2 leads wired to the blades that go into the wall. The other side has 3 leads going to a circuit board. The leads on either end go through diodes to the "+" output. The lead in the center (marked "C.T" - let me guess - center tap?) goes through a cylindrical glass fuse to the "-" output. There's a big capacitor (electrolytic? Black cylinder) between "+" and "-" and a few small (ceramic?) disk capacators scattered around. The fuse had shuffled off its mortal coil. I mean, even *before* I desoldered it. Which, BTW and of course, I think I did without damaging anything. This thing is so simple even I can almost understand it. Now I need a 3.7 (? something like that) Amp fuse with pigtails, and a couple screws, and who knows, maybe I'll be back in power. Definitely going to be a web-shopping day.
