ah now that is much better. the grey scale setup worked as it should, where as before the incorrect bias of the video out tube resulted in too high a plate voltage, that when connected thru the serice switch in the normal mode would tend to cut off the CRT. Now with the CRT bias set at the min, I can put it in service mode, just bring up each gun, and then go to normal mode and get a nice bright pic with correct grey scale. while at it I put the old focus coil back in and now have a best focus point, before in never quite got there.
I still need to double check all my HV setup for current and voltage, but it now has a very good bright pic, great color, and NO noise in the pic.
