If you say the whole circuit draws 500mA, you mean the total current of your HV circuit plus the LV circuit, right? You should measure how much of this 500mA is drawn by the HV circuit and how much by the LV circuit. If you're pumping 30mA through your nixie, it is not strange the HV circuit draws say 400mA, the question is then why does your LV circuit draw 100mA. Each input of your 75468 draws about 1.5mA when on, normally you have 6 of them on, one for each tube, say 10mA. If the current drawn when all is blanked is 5mA as you say, the LV circuit shouldn't draw much more than 15mA when all 6 tubes are on.
