Al, Phil and Jim. What I did was switch the blue and red plug on the

convergence board. If it were the STK?s blue and red should have 

changed position. That?s why I suspect a bad blue yoke. Every thing 

stayed the same. With plugs in correct position red and green 

convergence are perfect. Blue is pulled in on the right side about 

1/3 of the screen and bowed also down at the top, tapered down.

 

Numbers on the Yokes are all the same.  

 

Numbers on the CRT A17739-100-808-03 (170AGB22 (B))

Numbers on the Yoke 4414-01 under that 9511

covergence windings on the green, but red and blue were the same.
If you are changing yokes, save yourself the trouble retracing the 
harness by marking the color on the appropriate convergence plug.
