Thanks again Ken, your advice has been invaluable. I now know what to look at. I don't have a high voltage probe but when I touched the HOT with my multimeter, the meter jumped off the scale set at 600VDC. When I touched the ceramic resistor by X01, the voltage was back to 128 volts. I'll look into replacing the 2 transistors on the board. Just out of curiosity, I have the deflection wires from the tube connected to Q1& Q4 on the horizontal deflection circuit and Vertical on Q3 & Q5. I've been using the tube on an 8 liners chassis and broke apart the connecter to use on it. So I wasnt sure how the old connector went on the G07 chassis
