I am refurbishing a beautiful Philco 40-190 for a friend of mine. I've replaced all the resistors and caps after checking the service bulletins. However there is one resistor that I cannot find: The 10K resistor (1B) that is supposed to be in parallel with a 250 pf cap (1A). There is no sign of it every being there; the solder joints are obviously old. Could this be the result of another service bulletin?
