Thanks, I did try the magnetic strips (every place, really deep
too...) Those things clearly have an effect on the corners, but not
(much) on the sides and top/bottom.
Indeed the last set moves the magenta on green. (Thought because it's
called the green set it would move the green onto the magenta.....).

Allright, I tried following the Amplifone guide (which is a pretty
good step-by-step manual to do purity and convergence. It says to
align the first conv.ring with the gap in the canon area. Tried that
without much difference.

I ended up moving the ring set up to the yoke as far as possible. This
gave the best result I could get. It did reduce the amount of space
between the magenta lines at the top and bottom, but it's still not
perfect. However, because of this there is more area that looks good
(enough). It feels like if I could move it up a little bit further, it
would get perfect, but that's physically impossible because the yoke
is already as far as possible up the neck. (Which gave best purity).
All in all, I think the current picture is acceptable. I was surprised
to see that I hardly needed any metal strips for the corners. I did
use 3 to get it even better still in the corner area.

I think this is what my friend Luc will have to live with. While
playing the game, this will be looking good. Sure, if you start
reading texts it will show, but it is already 200% better compared to
how it was before I started the converging.

If I look at my own Amplifone I still can see some convergence errors
in the left lower corner. I think I can get this right with the
"magnetic" strips, as it looks like some of the original one's came
loose.

Maybe I'm just wanting too much for stuff that's almost 30 years
old.....try to find a TV of that age that still looks as nice as
this.... :)
