I guess the CRT is a 21CYP22, although I can't see any marks besides a serial number. Using 21CYP22 settings when testing it on my CR70 gave sensible results.
I made a makeshift fuse cap and the B+ lit up, but I didn't give it much voltage, and only did a very brief trial to confirm that there are signs of life. This set will have to wait its turn. When the time comes, I'll replace the p-s electrolytics before powering it up again.
