A guy here suggested:
https://www.aussiearcade.com/archive/in ... 38127.html"Some older high impedance CRT's start up cold blurry then sharpen up after 5 minutes. As in the arcade days it's on all day so it doesn't matter. Is your CRT a 12 pin type?
I have one that's been like it for 10 years & still running sharp, in focus & crisp but fuzzy for the first 5 minutes on cold start up. I wouldn't worry about it. "
I just wanted to ask you experts if you know the reason for the blurry startup, as my E2 didn't have this (that I ever noticed).
Thanks!
