I thought the same thing when I was recapping my model 20. I have the same wire coming out of a small hole in the phenolic board and going to the B-C resistor. It's also the only wire that appears to be rubber insulated. All the rest of the wiring on my chassis is braided cloth insulated. I'd sure like to know as well! Take care. Gary
