UPDATE, APRIL 25, 2019, DAY 268
From Mike: “Greetings. Here are the first “in focus” monochrome images of the set when jigged to a 21FBP22 crt. This is a milestone in the restoration process. There has been a minor setback with the Vertical Convergence Transformer and it has been bypassed in order to allow proper focus voltage to the crt. This jigging process will now allow me to do troubleshooting on the chroma circuits. There is no sign of color bars or color at this point.
Picture #1 Crosshatch pattern through the yoke frame with many vacuum tubes lit up keeping me warm in the shop.
Picture #2 Crosshatch pattern closer. Only center convergence and purity settings are possible with the 21FBP22 tube.
Pictures 3,4,5. Images from a show on antenna TV.
Cheers, Mike”
Author: Definitely a milestone Mike. We now know the chassis circuits are working to produce a picture. The convergence transformer may be arching internally. We are working to resolve the problem.
