Hi, I'm stumped(whats new) by a Barco Graphics 1208s/2 that I put new tubes into. The text comes up totally out of focus and the grid extends far beyond the edges of all the tubes. You can turn down the brightness and contrast to get the letters of the display readable(otherwise they are bloomed beyond readability) but at normaly levels you cannot achieve a proper focus. Am I missing something ? THey are the same exact tube model and I know the tubes are very strong. is there some static focus pot I'm missing or some aspect of setup I've overlooked ?
