Thank you for helping with this.
I have not yet put the CRT on my B&K 465 tester/restorer. The previous owner said the CRT has an open grid 2. I wanted to test it with the restored chassis first. I will test the CRT.
The vertical linearity and height controls do have an effect. I have worked to balance those, as well as the vertical hold. When I adjust the linearity, the vertical rolls, so I have to go back and forth. I have been able to improve the vertical linearity and width a bit, and now it is over-scanning a bit vertically.
Some new clues:
- When I turn the Horizontal Hold CCW, the screen goes dark.
- I was able to get an RF signal through the tuner. This was by accident, as I had the tuner on Ch 3, and switched the B&K 1077 channel to 2. Maybe tuner alignment.
