Here are pictures from Goodman of the CRT pole piece positioning for roundies.

Wow, small world. I have those two shots in a (one of many) book I have called "Color TV Servicing Made Easy" by Wayne Lemons and Carl Babcoke. It's a Sams publication and is wonderful. Guess that makes me look pretty bad, but there is a method behind my madness.

The book simply says to position the clover "directly over the convergence pole pieces." It even shows what that is as seen in the electron gun breakdown. My question was derived from the fact that the area is blacked out where you don't see the pole pieces. The blackened area clearly ends about where the clover should be. I thought perhaps the black line could be a reference point placed as the pole pieces can't be seen. I'm not sure of the distance toward the yoke that this black area goes.

I am trying not to move things a lot as I have pretty decent color. I have moved the clover enough to see that it's placement forward or back even a small distance makes a big difference in alignment. I guess I may as well just slide everything back and see if I can view the pole pieces. After all, I could be having to put in a new crt and be removing all of this stuff anyway. I just thought that if this were an indexing mark it would be nice and useful too.
