“I'm also still concerned about the brightness. It seems like the picture goes completely dark for a significant portion of the control. Not as much now that boost has been restored, but still more than I'd like”
Where are the screen controls set? jr

There doesn't appear to be any kine bias or brightness range adjustment. If it turns out more brt range is needed, there's a little bit of "engineering fudgery" that may improve it. Just jump a resistor from brt. control wiper to ground. I'd start with 2 meg to be conservative. Then work downward in R value till desired range is reached.
What it does is make the CRT cathodes more negative, hence the G1s more positive with respect to the cathodes. Again a decade box would be handy Last edited by old_coot88; 12-14-2019 at 11:26 PM. Reason: Typo
