Thinks its time to check the cathode voltages, CRT seems dark, even with the lower kv (22kv tops HV adj as high as it will go, still 1.6v drop (1.6ma) on the shunt tube) it seems like it should be brighter. The fact that I am not getting any contrast control makes me think the video amp is not right, perhaps cutting off the CRT. looks like I will have to pull the chassis soon to get much further.
