That sounds like a good idea. I will keep it in mind. Tonight I powered it up and it almost seemed like color wasn't going to come in. I started tweaking the killer and the tint and the color just came in. I REALLY need to get into some purity and static convergence when I get stronger tubes in there. I tested my 6KT8s on my Hickok and the Accurate Instruments for comparison. All good on the Accurate and all weak on the Pentode test with two having marginal triode tests. I used the stronger one of course. I think that the color takes so long to come in due to the marginal emission and a usually reduced line voltage causing slower. I have noticed that I can bump up the line voltage and shortly thereafter the color will come in; then I can back off to ensure the 200mA horizontal output cathode current and the color will remain.

Question: When I am setting up my convergence clover, is the black line on the crt's gun an index as to where the plastic edge of the clover should go to have it directly over the beam converging pole pieces? Some of this has been moved and I want to have it dead on so I can slide the yoke back and work my purity rings for a red center; then move the yoke back till I achieve the best red screen possible. This of course with the other two guns extinguished.
