I did try to discharge the CRT focus pin. No pop and wasn't able to read anything. No change in the picture.

I measured focus voltage again and it seems low, although this type of meter isn't exactly precise. As I mentioned earlier, the SAMS has a hand-drawn correction that says 3.5KV. One could argue this is almost 1/3 of the way to 10KV.

The focus divider isn't showing any physical issues. Are there other voltage points I should try?
