Easy to do?
Did a TV tube swap tonight, installed new caps and screen pot. After a problem with no blue that was traced to the interface board, I have a pretty nice picture.
Except for one thing - I can't get it completely focused. It starts dialing in, but just as it seems to be about to focus perfectly, I reach the end of the pot's travel motion.
So, I need to replace it, unless there is a way to add a resistor in series to make the pot range different (assuming the focus is on the upper end of the value and not the lower).
Unfortunately, my spare 4600 flyback is at work....
