Jens, Have you asked the poeple running this website: http://ericssonhistory.com/Default.aspx?epslanguage=EN ? They have a lot of old Ericsson manterial online which describe Ericsson products, amongst them the RYG10 Trochotron. I have not looked for any Nixie related material there but they might know. There are also other webpages in the UK mentioning the phones that Ericsson used to manufacture, I know that one such document also mentioned Dekatrons and that might also be a source for Nixie information. /Martin On Sunday, September 16, 2012 10:31:02 AM UTC+2, Jens Boos wrote:
