I am certain now of exactly what to do as far as proceeding with the repair of the burned socket which was without question. In my search for a replacement socket I was finding that some sets had the resistor and others (newer) didn't. I needed more information as my inclination was not to eliminate or alter something that was at least in my set. Now I can proceed with certainty and the information given is beyond helpful.
I still can't help but wonder how I had HV with the resistor burned in two. My only guess is that it was arching across the two burned open ends of the resistor. The burned out socket (pins 4 and 5) as well as same tube pins badly corroded may be further evidence backing this theory. Heck, pin 4 is a blank! Beyond a shadow of a doubt the resistor didn't burn any of the last number of times the set was in use.
Beyond the resistor topic my immediate concern will be that of HO cathode current being high at line potential. I doubt that this repair will correct that, but all of this is a learning process for me. Perhaps the issues mentioned and soon to be corrected do play a hand in that. I will know as soon as the socket arrives (hopefully later today). Lots of snow here for this part of the country which makes for a perfect day to work on electronics projects.
