Well I don't think it's going to work . I wired the tube up and powered up and got an out of focused picture really could not make anything out. Then the tube went dark then came back several times and I don't know why. The focus voltage should have been plenty for such a small tube since it's enough for a 3kp1 tube so I don't know. It appeared that all the controls worked good, horz, vert, all within where it should be except for the focus and clearity. I thought the cathode might be part of the problem since the heater is wired to the cathode in this tube but I was using a separate supply for the heater so it should not have had any affect, at least I think. The heater supply I'm using is ac so I don't know if that's got anything to do with it or why the screen was there then gone then came back . Should the heater be DC. Any hints......
