I can't express how much I appreciate the guidance you folks have been sending my way. Makes this task a learning experience..
So the recap continues along with checking resistor values. Have only found 1 resistor that hasn't measured almost right on as have all the others. Most have been within 3% of marked values. The one bad one was marked 10k and measured 251k

Next question regards a selenium rectifier within the filament string. I have yet to test it and am just wondering if I should just replace it since I'm in there.
Would a couple of 1N4007s do the trick? Part sheet just describes "selenium rectifier" nothing further. What purpose does this serve?
