[TA-A] Re: RCA Projection TV convergence problem

There where diodes that failed on that supply as well. You can also buy the 
kit for that supply from Tritronics part number: 250686-KIT. If you don't 
buy the kit, it's not really a hard fix. You probably will not need the 
schematic, just go over the components with your DMM.
