If tying to build one of these, the 6L6 heater needs a well insulated transformer. The H-K limit of a 6L6 (or most simalar tubes) is not 400V. The old tubes could take some abuse but the modern ones

Yes, to all of the above ! I like all of those presentations, but the main goal is the overall presentation, including what type of case it goes into. I've even mixed end view (IN-4) with side view

Hi: I'm inclining toward making some future Nixie clock designs follow this pattern, mainly to conserve the big expensive tubes. I'd prefer if the size ratio could be kept to about 1:0.66, but I think

Thanks for the comments, Michail. About

Oh yes, and it went for 70EUR... What a shame. Jens

Oh, I hadn't even noticed the analog meter! That is indeed a nice design! - John

Interesting. These are the first tubes I've seen which have worse quality than the Russian nixies. The Russian's aren't awful, just not as neat and polished as western ones. In particular, the popular

I have a bunch of Russian and Chinese tubes. The china are terrible. You would even think they were used and suffering from cathode poisoning (and maybe they are), but many do this within a month. I

Hmm, sounds like they may have been some version of the HDSP-2000? http://www.decadecounter.com/vta/articleview.php?item=750 These are Hewlett Packard 5x7 displays, four digits, in a small 12 pin

That's what I have been afraid of ;-) Oh thanks for the link, Eric. I am living in Aachen, Germany, so I technically could not be nearer to both Belgium and the Netherlands. Lucky me. Tell me about

Hmm I reckon they are, but a great deal of them is of very poor quality. I have bought 8 of these from a batch of 25, and 3 of my 8 show serious abnormalities in construction, i.e. the pins are not

US tubes are very scarce. 600 NL840s at Sphere's have diminished to just 23 in less than a year. Those may very well have been the last batch of National tubes in quantity that will ever appear. There
