Hello John, I think you have done very well indeed with this set. Seeing a b&w picture with the line linearity off brought back memories of the Solus regunned A61-120WR mono tubes we used to fit at Mastercare in the late 70s early 80s. Many suffered from corner shadowing on the top right hand corner (looking from the front), when set up correctly. Even with the scan coils pushed as far forward as they would go. The only way round this would be to off centre the picture to the left, this would just remove the shadow, then adjust the line lin coil or sleeve to stretch the picture on the right just enough to fill the gap. Non of the customers complained about the slight non linear line scan, after all they were just happy to have a picture of decent brightness again.

Alan.
