Try switching tube positions. Does the bright glow move? If not refer to @oddiofyl, if it moves replace the tube.
Problem with biasing
Hi, I have a citation 2 and recently re-tubed with gold lion kt88. I noticed that tube 8 was glowing a little more than the others. So I checked and it was 1.7 volts. My other tubes are 1 volt. Bias 1.68 volts is the lowest I can get which is still too high. Anyone ever have this happen?
