Yes...got up to step 16. A couple of questions before I proceed. I may need to go back and make some changes.
Where do I set the brightness and contrast controls? As I was starting with the potentiometer adjustment, I had a bright horizontal line which I suspected so I turned the brightness down. As I got further along, the line returned even with minimal brightness. I don't want to burn the tube so I adjusted the contrast to get rid of the line. All of this changed the -4.5V setting so I tweaked that a bit but now that I'm thinking about it, the appearance and disappearance of the line is due to the frequency changes I was feeding in?
I don't know. I guess what I need to know is where to set the brightness and contrast from the beginning and what to do if I see voltage on the pot controlled monitoring spot varying from -4.5V?
