The center "tap" is the yellow with green tracer wire coming from the PT. Given that the wire colors will be faded and dirty, you'll have to trace it out. It will be connected to the negative of the lytics, to one side of R25 (200 ohm) and to one side of R21 (1 meg).
The field coil will be two of the 4 wires coming from the speaker. One side of the coil connects directly to the filament on the rectifier - either pin 7 or 8. The other side is going to connect to R31, R7, R11 and the red lead from the 1st and 2nd IF cans.
