You can download Motorola service info from the Early TV Foundation here: http://www.earlytelevision.org/tv_sc..._motorola.html

I belivebe the only mistake with the Sams is showing some of the filament bypass caps going to B- when they should be the chassis.

They changed the ballast tube and the contrast control circuit from the early to late TS-4J. There may be other very minor differences. The power supply circuit is the same.
