a video would be a good idea of what you have now. Show some reg color programing and adjust the fine tuning from smear to wormey

before touching any coils you really need to eliminate all other possible issues. diddle stick drift is the worst thing to deal with.

based on the video it should be determined that the color osc is running and or synced properly. color killer is also an issue. There is a lot that cause the color circuits to not work right, coils adjustment would be the last place to look, esp if the osc is not running or is WAY off. any tweeks would be minor UNLESS someone has gotten into it (the reference to diddle stick drift).

of all the color sets I have worked on with respect to coil adjustments, the most that was required was a 1/4 turn on coil in the osc circuit (rare). Most of the time it was a dirty pin/weak tube/cap/pot issue. Its aways best to start with the obvious and easy. fine tuning and signal 1st, Tubes in chroma, wiring from controls, the pots themselves, settings of color killer.

To the others that are helping, I am pretty sure the OP has not touched any of the now suspect film caps in the chroma circuits.
