The Horizontal output cathode current is right around 200ma. So I guess it's okay. But how would I adjust it if it weren't okay? I had a 6BK4 pull kicking around so I put it in. No more "blooming" but the picture still takes about 15 minutes to get bright and it doesn't seem to get as bright as it did with the other (older/weaker?) 6BK4. I have a new one on it's way. But I still suspect that the original suspicions were correct. It needs a new CRT. So what to do now?
