Alright, so I got another tube on, flipped it on... nothing happens. Try again, nothing happens. Check all the chips to see if they're warm, all are cold. About now I notice the ground wire smoking where it's exposed between the two clock sections (AFAIK it's the only thing that got hot), so I quickly unplug everything and go to pick it up (by the nixie power supply, since it's big and sturdy), then I notice that it's really hot on the side, and I realize that it's only 12mA, not 18...
My theory, I over currented the power supply (5 nixies and 2 neons), and it fried inside, and sent a bunch of power to the ground, which went backwards to the v+ line and killed everything, but I'm not sure. I'm going to remove it and see if the chips still work, because I really don't know why the ground line would have smoked like that.
For now I'm going to try to remove the nixie power supply and see if the chips work, if not I'll replace them all and hope the transistors survived. If not I'm printing a PCB.
In the mean time, if anyone has any ideas on what might have happened I'm open to all suggestions and ideas, because I would have thought they would at least light up for a second...
(also, if anyone knows any power supply schematics that can put out a lot of current, I'd appreciate it)
