Is there a trick to setting purity?
I went about setting the purity on the Avanti set today. I was told to orient the set east to west when doing so (CRT screen facing west and yoke facing east). I followed all instructions, but could not get a red dot on the screen. The best I could get was about 70% of screen coverage and no smaller. I went about adjusting the rings and managed to get the center of the screen pretty red and then I just forward the yoke. As I moved it, the red didn't stay pure. A little more tinkering and I finally got the entire screen red and locked the yoke back down.
Well I moved the set 90 degrees and now the on screen colors vary across the screen. Some areas a little more red, some a little more green, etc. I'm assuming this is because of the magnetic field? If so, what do I need to do to adjust the purity so it doesn't change as I move the set around? I'm sure it's possible because no other set I have changes. Hmmm.... Thanks
