You may need to adjust L86 (sams). It sets the relative phase angles of the demodulators...If it is off you will be able to get the red bar red and the blue bar blue but not both at once (and similar problems)... IIRC you have to adjust a slug on top of chassis and a slug under chassis simultaneously with plastic* straight edge alignment screwdrivers (had to do this on my CTC-4). *Metal screw drivers will act like an extension of the slug and your freshly tuned adjustments will de-tune as the metal driver is withdrawn from the transformer can (spoken from experience
 ). If the color temp is right with the set operating in B&W mode then it is right, and does not need messing with....If turning on the color circuits throws the greyscale color temp off then there are problems in the color circuits causing that. EDIT: BTW congrats on getting sync! It seems these sets like to get dirty intermittent tube sockets.
