Also, some high powered tubes that take a lot of filament/heater current
(rectifiers for one) will also make that bulb glimmer or show a little glow.
Be sure you let the tester warm up at least 5 mins. and be sure to set the line adjust correctly. Once a heavy current tube is warmed up, I always re-check the Line Adjust and tweek it if necessary before test.
