Hello everyone, i started a project for a nixie clock and after a few hours of searching i found this one
i made the pcb, i had to modify the shield for tubes, but now i am facing a problem, at first i powered the main pcb with no ic in socket, everything ok, time to insert 555 and check the high voltage, it draws 360ma and the high voltage is missing, i noticed i mounted D1 the wrong way. i fixed this, now it draws 2A and i still have no high voltage, but now i only have 2v on the output of the voltage regulator...
