I tried to bring that Colorama back to life using my B&K 470 and 445. I clean and balanced the tube twice, then rejuvenated it twice. After that didn't work, I tried to dynamically intensify the non existent green with the 445. It helped a little. That tube is history. The picture is after using the 470 four times.

Monochrome sets often can still make a decent picture like that, but colors depend on the guns having relatively similar emission, and often don't focus well as they die.

Changed the picture tube in the Winslow today. Took out the super strong - almost brand new 1972 Zenith 23VBAP22 black matrix tube, and put in a 60's RCA tube that was rebuilt in 1980 by an Atlanta company called Video Display. I want to save the Zenith Chromacolor tube for a deserving Zenith 23" set, if I ever get one. I want the set to be as good as the tube though. Mint condition, remote, and a cabinet I really like.
Here you can see why I prize that Zenith CRT so much. The last picture is how it tests at 6.3 volts. I have never seen any other CRT test so good.
