CTC-7: Convergence, Convergence, Convergence

[jbeary]

Hello All,

Can anyone let me know how come I can’t ever get a perfectly round dot from my dot generator? It’s not the dot generator because it works fine on the new TV which is perfectly converged… Because I can’t get a good dot, I can never get really good convergence and it’s making me crazy.

Could this be caused by having the elements out of whack? Can anyone post a diagram or pics for a CTC-7 neck; maybe with some measurements just to make sure? I get really good purity, but each dot is a different oblong shape. And while I can more or less line them up, the convergence is always off on one side of the screen or the other toward the end of the process.

I’m hooking up the generator through the tuner but no matter how I tune the fine tuning; the dot shape remains the same. Should I be going straight into the video signal to eliminate this? If so, can some one please let me know how to do that on a CTC-7 chassis with that horizontial trigger thingy?

THANK YOU ALL in advance for your help.

Jeff
