1963 Philco

[Adam]

All that stuff I did yesterday that I thought fixed this, didn't. Now the only color I'm getting is green, even if I let the set warm up for a while. And it's not that the blue and red guns don't work at all, because I can get a good b/w picture, just not a color picture with anything but white and green. I also get a good red, green, and blue horizontal line when I flip the service switch. Now according to the schematic down below, the voltage at the plate of the burst amp tube should be 50v, I have 400v. Is that a misprint or is it supposed to be 50v? If it is supposed to be 50v and not 400v, I can't find any components in that area that are bad that could be causing that. Now the 6EW6 is definetly good (and I tried another one too), but if I remove the tube while the set is running, there is no difference in the picture whatsoever. And the tint control has no effect as well. Any thoughts?
