Also be prepared to degauss the set again if you move it to another place after doing the final setup & convergence.
This article describes some of my adventures in learning how to converge my first CTC-11:

If you're lucky, you will not need to do so many repairs along the way.
The Pict-O-Guide is well written and very informative, but I followed the Sams convergence instructions and (eventually!) got good results. There's no shame in repeating a procedure; it may take a while to get the hang of what various adjusters actually do. And, as already mentioned, you may need to accept some little compromises in the end.
