Good morning,
I have recently purchased a Modular Nixie Clock Rev3 kit for IN-14 tubes.

It works quite well, but after some days on i have a strange issue: in one of the tubes more than one digits remain activated at the same time.
I've tried to fix editing some parameter related to HV section, but i can't understand exactly as i should do.
It's a gift, so i would like to make it working perfectly.

Some months ago, I have assembled also others kit, working like a charm!

Someone can help me?

Only in one of the tubes? That is strange! What happens if you put that tube in a different position, or IOW swap it with another tube? Does the problem stay with the tube or with the position?

Look into it later when the dust is clearing off the crater.

Hi!
No, not only in one. The clock is fully assembled, so I haven't tried to swap.
Up to now, i've noticed randomly in the "1s Hours" and in the "10s Seconds".
This strange behaviour happen after hours of good working.
To be honest, tubes seems flickering a little, at least compared to mine working on shelf from more than year, but i don't know if it is related.

I can try to change the driver (i have 74141N as spare available), can be useful?

Yes please try changing the driver. I can not think of any other reason except bad driver for what is happening.

Also - if you have changed any of the HV config settings I recommend doing a factory reset when you change the driver.
