CTC-16 combo

[DaveWM]

Bill try as I may I can't get the red blob in the middle (the procedure you described is what I did). Red screen up, yoke back, best I can do is get the red in the middle/and left side. I normally can get the red blob and have the blue and green sort of around it in 3 separate clouds. This one just does not want to behave. I try rotating the rings together as well as operating them separately, and a combo of both (rotate together and try apart).

I did not try the grey scale tracking with brightness will get back to you on that.

those rings usually dont go bad.try another yoke?had a 15 back 25-30 years ago that had the same issue.was a bad yoke.we played with it for a few days and changed it out.took care of the problem

roger that I have a NOS yoke just looking for a home.

I am sure there is something up, I have done roundies before that worked just fine on the purity setup.
