"Discharge wand was a cabinet knob with a small brass rod screwed into the threaded hole to keep the knob pointed forward. Ground wire clips to back of rod. The tube itself is one of those cheap clear plastic tubes that fit over a fluorescent bulb. The problem is that static electricity is very persnickity. Sometimes it works. Sometimes it doesn't. Could be variations in humidity.The tube tends to build up a charge like a capacitor. Try different knobs, distances from tube to terminal, etc."
