Why is the CRT taking longer to light up?

[Phil Nelson]

I have learned to clean the tube pins (and test tubes) first, before attempting any service. As Tubejunke points out, that can save embarrassing head-scratching later on.

Tube pins aren't so delicate that you need to fear cleaning them. I have brightened up many, many of them using fine sandpaper or a scraper, with no problem.
