Well after being busy for months I finally removed all but 1/4" of the flyback "tire" on the CTC4, isolated the loose end, and then hooked up one of these to the horz. output as suggested here-

BUT up firing up the tripler promptly split open with a loud crack. Back to the drawing board- was I not supposed to ground the "Reference" terminal? That's what I saw on nearly every diagram, can't see it working without such. I had horz. output cap voltage to IN and obviously the orange high voltage lead to the terminal on the bottom of the high voltage rectifier tube which I left out. Thanks for feedback, this is all a bit experimental obviously. Perhaps tripler was simply defective or not high enough rated? My best guess is arcing somewhere overloaded it milliamp-wise. But the high voltage "rail" (at rectifier socket) reads infinite to ground.
