Part 46 in the pictorial doesn't have any resistors connected to lug 2. As Terry said, there's two components connected to lug 1 which is a ground terminal. There should be a wire from lug 2 and 3, one to the transformer primary and the other to the power on/off switch. In addition, one of the power cord wires should be connected to lug 2 and the other to 3. Neither the schematic nor the pictorial show a second block. If your radio has a second block then someone has added it and discovering what components are attached will help to determine how and where it is wired.
