John . I did change R70 it was about 47K I didn’t think that too bad to start but thinking about it that must be about 20% over the odds. I didn’t notice too much difference apart from slight increase in width. I been playing about with a extra magnet to take out the curvature on the left of the picture. I have had good results but the horizontals on the test card slightly curve at the edge. I think though that’s about the best I’m going to get it.

I do have a slight increase in height switching between 625 and 405.

John (H/C) well I’m glad people like yourself help me on the internet. I might open a new thread as I’m not sure everyone had so much knowledge.

Andy.
