I have come to a dilemma, and hope those more expert than I, who have dealt with this model radio can give me some guidance. As I am delving into the power - final audio end of the receiver, I am making a careful map of everything, and where it goes, and where it connects. In doing so I have come to a problem about part 51. On the schematic, and in the parts list it is shown to be a 70K resistor, yet in the radio itself it appears to be a 10K resistor, and it appears to be original and never changed. Was this a mistake in construction, or a change made along the way which I haven't seen in the notes? What was it in your own 37-640s? I would appreciate any advice about this. Here are pertinent pictures...
