[vcf-midatlantic] Anyone ever adjust the yoke on a 1970’s Sony trinitron?

[Matt Patoray]

Corey,
Put the rubber wedges back in place. 
They are there to keep the yoke positioned properly front to back on the tube.
Loosen the screw then the yoke should rotate. Square the image up on the screen.
Then tighten the screw again, just slightly more then snug.

You may have to slightly touch up the H-Stat convergence, which should be on the flyback along with focus.

I decided to walk away for a few hours and just took another look and I did just notice there is a small clamp on the end of the tube neck that could be loosened up, but before I do that I was wondering if that is what it’s intended for to hold the yoke in place against the rubber wedges?  I don’t want to have to adjust the convergence so I haven’t loosed it yet just Incase that is wrong.  I’m also worried because the neck is the most fragile part of the tube and don’t want to break it.
