Having worked in semiconductor industry all my life with plasmas inside vacuum chambers I can tell you an air (nitrogen) leak would show up as an orange glow. That is gas but likely something internal which off gassed over the life of the tube. Depending on the species, plasmas can often emit harmful UV so be careful what you are staring at!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1146246558798303856.post-60165122753298110162018-12-28T16:05:03.645-05:002018-12-28T16:05:03.645-05:00Well done Richard.Well done Richard.Robhttps://www.blogger.com/profile/02617133904969374816noreply@blogger.com
