All CCIIs have a focus control. Have you tried adjust it? If it's at one end (I presume you have it set for minimum voltage and best focus) one of the resistors may have drifted.... Often the HV divider resistor (which is often part of the trippler) has drifted...if the special HV five resistor has drifted you can often unhook the end of the focus pot opposite of the end the wiper is on and insert 1-15Meg ohms (it'll take some guess and check work) worth...

Thank you for chiming in. I was pretty sure focus was attained in the middle of the pot's travel, so I double checked, and the best setting is almost exactly in the center. BTW, YouTube's magic spy algorithms suddenly suggested this video after I read your post. My set doesn't use a focus divider like this 25DC56, but otherwise appears similar.
