The ZM1040/ZM1042 are 30mm height and also have very nicely formed digits. Prices range from ~$40-$60 per tube. The Z566 is also the same size digit. There are many variations in the envelope style as there were several manufacturers. You can find both rounded top and tops that have the evacuation peak.
The IN-18 tube is a 40mm height digit and prices have increased dramatically in the last two years and will cost ~$55-$65 each. I have only seen the Russian tubes and they all have the rounded envelope top. Both ZM1040 and IN-18 tube types are available on eBay as of today, but you won’t find under $30/tube… Jeff From: [email protected] [mailto:[email protected]] On Behalf Of gregebert Sent: Thursday, February 25, 2016 1:43 PM To: neonixie-l Subject: Re: [neonixie-l] Looking for large tubes IN-18's are your best option for large "affordable" nixies. At 40mm character height, and perfect digit shape (no upside-down 2's for '5') . Recently the price for six IN-18's has gone from around $220 US to $350. Luckily I bought what I needed for my 14-tube 'tomorrowland' clock before the price went up. I've bought from several Ebay sellers in Ukraine, and all of them were honest. I can't vouch for IN-18 reliability because I havn't put many hours of usage on mine; others in this forum have indicated generally good-reliability, except for certain date-codes (1982, and possibly 1986 if I recall, were the problematic ones). Supposedly the 'OTK' stamp is a good indication, but I cant confirm that because all mine are marked OTK. Be careful with the pins; most of the IN-18 tubes I have use a softer material so they bend very easily. But I do have one manufactured in 1977 that has stiffer and shiny pins. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
