CTC-5 IF alignment, chassis in or out?

[CJVx]

Hello, after a full recap and convergence adjustment, I feel my CTC5 is need of a sound and video alignment as I am having issues with the best sound and the best picture not happening at the same time, nor am I getting very successful color AFC results as per SAMS procedure.

The manuals say to disable the horizontal by removing the fuse, and adding a load to the B+. Certain other steps allude to performing the IF alignments to a chassis on a bench top, out of the TV, no yolk connected etc.For this model, is this correct? Any experienced folk have any particular tips or quirks on this model? I’m have a Leader LSW-333 and a Sencore SM-152 sweep
Generators and have built the detector probe as per the manual as well as a decent oscilloscope.
