Ive got a pair of 4412's and one of them has a tweeter not working. The tweeter is good and the volume adjustment pot that is in line is good. (switched them with the one that is working.) So I have narrowed it down to the xover. Now the question is to meter caps and transformers and coils can they stay on the board connected or do they need to be taken off the board to meter?

Do an A:B comparison between the crossovers. When you find a difference, start there. Only when you find a measurable difference should you mess with removing components from the board(s). BUT....
I strongly suggest that you shotgun all the caps as they are typically the first thing to go. And if any one of them is bad, the rest will not be far behind. Remember to us NON-POLARIZED caps when electrolytics, and high quality film caps otherwise. Screen them for values beyond what is written on them. No need for boutique caps, just high-quality caps of the correct voltage and value. Match the *values* exactly to what is in place (OK, you may use a .47uF instead of a .50uF) as well.
