Ok finally got back on the radio this weekend. It doesn't look like anyone messed with the wiring, as it crumbled when I began working on it. The only repair I saw was the 10uf electrolytic had been replaced at some time. The 80 I had replaced because it tested weak, no change. I found R 10, and R 11 out of value. I replaced R 10, and have R11 ordered. Just for kicks I pulled the 47 tube out of the circuit, powered up, and probably 95% of the buzz went away. Put it back in the circuit, grounded G1 to the chassis, powered up, and had very little buzz, but also no audio. Unclipped the G1 lead from the chassis, audio with the background buzz came back. Would I have a malfunctioning 47 tube then?
