The main power supply for my ancient Laserjet IIp+ printer has given up. Fuse is not blown. Power switch has continuity... don't feel like trying to debug and repair the "brick". There are two Sony labels: One says Model RG1-1782 (I think that's the HP part number) and the other Model CD-91A, 100-115V. Does anyone have a working one in their junkbox? This is the LAST time I repair it before it goes to the recycler! I think I've changed every module except this one. It has become my grandfather's axe: new head and new handle, but it's still my grandfather's axe :) thanks Charles
