Hi Marc,
Many thanks for posting the pictures of the scan coils. They look far too clean: I haven't dug mine out of the filth yet but they do look to be the same, so I haven't got a bit missing.
Looking at your second picture, you can see the clamp which holds it on to the tube neck just a bit back from the tube base. What is the purpose of the aluminium ring just in front of the shift magnets? This can slide back and forward about 1/2 inch. What does it do? Also what stops it from moving, my one wabbles about in the breeze!
Just the other side of the clamp is a steel ring, directly in contact with the glass. Any idea what the purpose of that is?
Many thanks
Nick
