When viewing the video segments, keep in mind that all three cathode emissions are extremely low, especially the red. Video consists of a brief history, screenshots and three video clips.
Lots of moire and my camera lost focus numerous times. Haven’t had this problem with other sets. I wonder if it has something to do with post deflection focusing by the CRT?
