The yoke is held by the clamp yes.
The convergence will be affected by removing the wedges.
They are used to tweak the purity (of red) and convergence.
If you move the yoke at all the convergence and possibly purity will be changed.
It my take some time but you should be able to " get it back".
You could bring it to the workshop
Plenty of people to help I'm sure.

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.
