Done that. No shortage of high voltage here. No glow ... no gas ...no joy. The tube is stashed in a safe area. On Thursday, July 23, 2015 at 1:18:04 AM UTC-7, Dalibor wrote: > > Hi, try touching CRT monitor or plasma globe with the dud tube. If there > is neon, it will glow orange inside. Usuall

[neonixie-l] Re: F9020 Nixies

Over the years I have been known to add a few too many buttons or switches to designs, but I would struggle to come up with half the number Patek managed to on some of those clocks. Amazing pieces of over complication... -- You received this message because you are subscribed to the Google Grou

Hi, try touching CRT monitor or plasma globe with the dud tube. If there is neon, it will glow orange inside. Usually the bad tubes are leaky and don't glow or the glow is a bit purple - sign of a bit of air sucked inside. If this is the cause, the leaky place would have to be sealed and the tub

[neonixie-l] Re: F9020 Nixies

Any obvious signs why your F9020 is dead ? If there is an inherent manufacturing problem with this tube, perhaps due to it's unconventional shape, it could explain why they are so rare. There were probably billions of round vacuum tubes produced so I'm sure all the obscure problems were solved

[neonixie-l] Re: F9020 Nixies

I have a dud of one of those. It would be great if it had gas and worked, but no such luck. If it was working, it would be worth a lot of money. Mine is just a non-working paper weight. On Monday, July 20, 2015 at 7:43:17 AM UTC-7, Raymond Koonce wrote: > > I have an acquaintance who is looking

Posting a link to the datasheet: http://www.jb-electronics.de/html/elektronik/nixies/n_f9020aa.htm Very unusual tube because it's flat-ish, and all pins are inline rather than a circular footprint. Unfortunate these were not more common because they have obvious space-saving advantages over rou

10K Euro would probably not be out of the question for this person. I'd just like to be able to find some for him. On Monday, July 20, 2015 at 10:46:55 AM UTC-5, Nick wrote: > > On Monday, 20 July 2015 16:33:13 UTC+1, Terry S wrote: >> >> Can you post pictures of the clock? >> > > Good plan! If

[neonixie-l] Re: F9020 Nixies

There has been a suggestion in the past that these tubes were made by CSF specifically for Patek and possibly Omega - they were certainly never in mass production. I have an idea though - we have a member here who can actually MAKE new tubes - Dalibor Farmy - a re

Thanks for the reply. That's sort of what I expected, but I thought this would be a good place to look. The interested party is in the antiques business and has some *very* expensive Patek Philippe clocks, as you can see here: http://www.rauantiques.com/search/?start=0&q=patek%20philippe&sort

Hah! Probably not a chance. I have a couple, but I've seen almost none come up for auction in 15 years. A member here did come across a cache of them some years ago, but I believe they all sold (for a LOT of money). Nick On Monday, 20 July 2015 15:43:17 UTC+1, Raymond Koonce wrote: > > I have
