The big problem was that R8 was disconnected from the cathode of the detector tube. The other problems were that the leads to the IF transformers were shorting against the metal can where they exited from it because the cloth deteriorated.
Why someone would cut that wire, I have no idea. It was done many years before the late 70s when I got the radio. The chassis says Westinghouse WR-10A on the back of it and it's in a tall "Columnaire" cabinet. It looks like "Columnaire 12A" with an electric clock in it. WR-10A refers to a "columette" 10A which is normally in a Tombstone cabinet, just like the R-7A. So I have no idea what the model number of this radio is. But it's one of my favorites. It's going to look really good in my living room.
