turned it on and wow, solid blue screen, I was able to turn the background control to about the 1/2 way, and now since I was not limited to brighness (and greyscale to the weakest color blue) I was able to increase the overall brightness to what is pretty much normal for all my color sets.

I am getting a bit tired so will leave the checking of the screen voltages to later, but one of those (or both) resistors was really a problem (the 10k that was 16k or the 1 meg that was 6 meg).

Still no blooming at all, I don't know why you guys with 5's are having such low HV voltage and regulation issues, this one seems rock solid. All I did was make sure I had good HV tubes and I did change out the 83k to 120k plate load resistor on the horz board, but that was just to get the fly current as low as possilbe with out a drive bar (there is just a hint of one in there now, 100k would prob be perfect). Iam getting a solid 22kv with plenty of head room.



My recommendation to folks having low brightness, remember to check voltages at the CRT.
