Nick, I have gotten this process down to a 'science', I think. The best way i have found to vet these things, because they are just plain flaky, is to set up a mass burn in station. By that I mean, set up a station where you can burn in several, I usually do 5 or 6, and let them burn in for at least a 3 -4 days each. I found that after that time period , if they're OK and exhibiting no* noticeable 'wobbling'*, you have a winner. See attached . I also make sure to make the raised dot side hot ( although I'm not sure that makes a whole lot of difference). There is a raised dot in the glass envelope on the base of these things that I think indicates the Cathode side, although there seems to be uncertainty about that too. Anyway, using this method I have ended up with several INS-1's that have lasted over 10 years and no wobbling. As some of you may know, I am sort of obsessed with using these things as center eyes in my clock designs. Can send pics of how I set this up. Right now for some reason I am unable to upload pics to this post
