Hi All,
Am new to TubeCLock db so I am hoping someone can help, apologies if this out of section.
I do not know an awful lot about nixie and its components but looking for some advice.
I have owned this ebay purchase for a year, I can find no details about it but recently it has started to lose time. Approx 5 minutes every hour.

Part curiosity about it's design and part annoyance has driven me to want to fix this problem.

The Clock is shown in the attachments it is a "TIMEON" clock made in Rickmansworth England engraved on the based.

Can any one offer a fix for the time lose or is this just expected over the lifetime? What would I need to replace to fix it?

Many Thanks in advance.
Ali

Your attachments did not post. Please try again. If you were using Firefox to post, try using a different browser because for some reason Firefox never seems to work for posting attachments to this site.

About your clock losing time... this is only a wild guess but did you recently move to a different country, one with 50Hz mains power instead of 60Hz? Many "old school" Nixie clocks keep time by counting the mains powerline frequency.

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

Thanks for the response.
Hopefully attachments included now.

Interestingly when I cast my mind back this did start occurring when I moved house, but that was only from London to Norfolk on the east coast of the UK.

So the power frequency is the same 50hz and I cannot believe there is this much power grid/provider variation in frequency to affect the time this much.

Any definite way of checking? Or work around or fixes known?

Thanks
Ali

Glad to see your attachments now work, because I didn't have any good answer for why they were failing. In fact I just did a test a few minutes ago using Chrome and my attachment posted normally...

Okay... you really need to see this:

While it's not exactly the same unit as your clock, I'd say yours is probably using a motor for timing (how very odd!) like the one I've linked. So perhaps the problem is as simple as a dry bearing (bushing?) or something of the sort?

Is the clock plugged in to a ups? Or something next to it could be messing with its ability to detect the power frequency?

Just a thought
