Your post was most interesting to me since I never realized that the spark gaps worked as negative resistance devices. My take was that they generated a wide spectrum of RF junk which was filtered by the tank (sort of like a class C amp).
I do not take issue with what you wrote but I would like to ask if you know of any work with glow tubes (also negative resistance devices) which might have been tried?
