I've seen a burned spot in quite a few sets from the late 50s/early 60s. That's when the switch to 110 degrees and high anode voltage happened. The images became brighter but spot burn seemed to become a more serious issue. Especially on 21" and larger screens. I'm thinking because they had more surface area for the aquadag forming a HV filter cap.
