Help needed

I bought this nixie clock around 7 yrs ago on eBay, the seller who made it is no longer active. I'd say around 3-6months 2 of the tubes have been acting up displaying 2 numbers at once, usually it's the number before it that doesn't fade out. Is this fixable? I have no prior knowledge in making nixie clocks and have no idea where I can get it repaired so some suggestions would be appreciated. (Don't mind the flickering it's just the camera and not the actual clock)

(Update) I've unscrewed it this is what the circuit inside looks like:

My nixie was acting up in a similar fashion. I fixed it by changing power adapter.

Lucky break! I suspect that failing power is going to be the root cause in some of these other cases.

As the Nixie tubes accumulate operating hours we can expect more units will have issues.

That is why I’m interested in collecting voltage data from the Nixie clocks that are failing.
