Something is wrong. My project (Bitcoin Ticker) uses 8x IN-12B and they (hundreds of tubes worth) don’t have that issue). I used the 12B since it has a decimal point on both sides. Have you tried another tube? What’s your project schematic?

I finally tried that but I don't like it. Is anyone using the decimal point of an IN-12B in a project? When combined with a 3 or 8, the point is barely noticeable. Another problem I'm having is that it glows much brighter when no digit is lit. As soon as a digit is lit, it gets dimmer. Is this normal or I’m doing something wrong? I use a 15K anode resistor and an 82K cathode resistor for the decimal point with a voltage of 170V.
