Thanks a lot, it is very helpful! I don't have any sound at all. That would have been my next task to look into. Guess I might as well buy a spare of the other valves as well. I didn't get to adjust the AGC - this would require that I have a signal on that it would sync to, right?

The LOPT has also been a fear of mine, but it seems to run cool - using an infrared thermometer to measure it, so I didn't give it much more thought. My method is otherwise also just try running it in shorter time intervals and let it cool off. The LOPT (AT2023/21) looks very close to unused. Replaced the booster cap (56n) with a new one, just to be sure.

On the pictures, the brightness control is only at about 75% of max, but need to make some more measurements to know that the pot is ok. The problem with this TV is that the side panel with adjustments rotates inwards just behind the CRT, and don't want to fumble around too much in that area when the set is on.
