I was able to get a raster, albeit a very dim one, and the only way I could get the raster to appear was with the brightness control set in the middle, if i turn the brightness control all the way up the picture disapears, and if I turn it all the way down the picture disappears as well, it only shows up when the brightness control is set in the middle.
Sounds like the raster is 'blooming' from HV sag. Have you subbed the HV rectifier tube?
