Lifesaver for those badly magnetized CRT's.If the CRT is really messed up the built in degaussing coil just won't do the trick,Weller solder gun just doesn't cover enough area-it may work but I would think it would take quite a few trys to get her done. When I was in TV field service many moons ago,this was the gauranteed first time, everytime cure for the magnetized screen.
