So I tried going through the setup as indicated by the manual and I couldnt even get past screen temp without an issue. I followed the instructions in the manual. I couldnt get the "barely visible red screen" and I think I know why. I went to measure the bias on the Red grid and cathode as i adjusted the brightness and the voltage was way too low. Im talking almost 200v below the intended 70v. I did have all controls adjusted correctly while checking the bias and adjusting the brightness for a dim red raster. I suspect a resistor downstream of the red screen control or downstream of the cathode and grid has drifted way too low or has even shorted. I guess ill have to do some investigation. This all seems odd since I at one point did have red in my color picture and things looked pretty watchable, but now its kinda taking a turn for the worse. I have one picture attached of what it used to look like before I really recapped any paper caps.
