I recently picked up a carbon arc trouper that had been converted to xenon at some point, mid-80s if I were to guess. Everything is functional and the whole setup is pretty interesting, but someone along the line made a few questionable choices, which I'm slowly working on rectifying (Example: someone wired the fan on a separate switch that allows it to be freely turned on and off with the spot still on). I'm mainly after documentation on the Kni-Tron rectifier side of things, anything more than an advertisement that would allow me to double-check the previous owner's work. Everything from a safety standpoint is already fixed, I just want to attempt to bring it back to a "by the book" conversion. I emailed the company (or at least what's left of it) and got no response, so this is my next option. It seems a similar, if not identical rectifier is still sold by Kneisley, for a specialty application. The specific model I have is no.M65RAX1C1, but I'm sure they have the same thing under several model numbers as well.
