I have the problem with all my IN-12B... Schematic of the display: https://github.com/axtar/Nixie-Calculator/blob/main/Schematics/Schematic_Nixie_Calculator_IN-12_Display_Rev2.pdf If using the B version I populate the 82K resistors. If using the A version, I populate the neons and the 270K resistors.
