My First Color TV! (RCA CT-100)

[benman94]

There's an old timer in the Detroit area who insists he worked on a CT-100 that was modified to use a later magnetic deflection tube. The convergence assembly and convergence yoke were replaced with parts from a later CTC-4 or 5, and the new CRT was connected to the existing 19.5 kV HT supply. The drive voltages for each gun had to be tweaked as well. He said it didn't work very well, and was really an enormous waste of time and energy.
