fascinating the picture I just took and uploaded was different than it looks now. Turn on tv take picture upload picture. Uploaded picture is with no warm up time. Picture gets shrunk some as it warms up and might even be clearer after warm up. I have put focus coil as close to yoke as possable and square to the tube. Latest picture of trying to dial it in. Makes me wonder if focus coil needs to be closer to yoke. I dont know what made image clearer, straightening of the focus coil or make it closer to yoke. Now picture seems to be oblong on right side but if I measure top to bottom and left to right its 6.5 inches for circle. Also is more pickey for horizontal lock so somethings out of adjustment because if the cables loose and I bump it introducing static it wont lock back on and picture tears unless I readjust it so must make sense, looks wonky and doesnt horizontally lock good. Oh the joys of tweaking not knowing what your doing. I try to adjust it so everything looks good and I get this line so I back it off and my pictures messed up some way or another. No idea why this line appears then dissappears depending on what Im tweaking.
