60's color motorola

[DavGoodlin]

The round indicator between the hue and intensity controls is will light red when a burst signal is present (indicating color broadcast with correct fine tuning).
In 1965 there were many BW programs and unless color was being broadcast, you did not want to try adjusting those two controls in vain.

Have you tried swapping the five 6BL8 tubes in chroma stages? That would be a good start. If you take the two chroma IF 6BL8s and swap them with the two demod tubes, then swap the color sync amp, FINALLY go after that 6GH8, used as the color osc, you'll need a new one to be sure, those were troublemakers.

When you move set up switch, I was taught to bring each G2 screen control up (these are behind the escutcheon under the brightness and contrast controls) and back it off until the line just disappears, repeat for all three colors. You should have a fairly gray picture when you are done, only then you adjust the green and blue drive controls to finish up. Then turn up the master G2 control next to the screen controls to get the needed brightness.
