Turned on tv for first time since last two remaining electrolytic capacitors (they were on pincushion board) replaced. No noticeable improvements but not worse off either I suppose. The HV anode cup is quit rigid due to age. Could the anode cup being rigid cause any issue when trying to measure HV or cause issues with the raster or picture in any way? Is it a good or a bad idea to replace the anode cup? It does not seem to be a particularly costly thing to replace luckily as they were commonly made for many decades after vacuum tube tvs stopped being made since CRTs were still a thing into the 2000s.
Here is a image of what it looks like with a grid pattern on the screen. Seems to be possibly still having linearity issues or pincushion issues? Or do I just need to adjust control more?
