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.
