One of the plates is connected to the blue wire the other to the brown. Red wire is the hv feed which is connected to the screen grid. On the secondary if you look at the old transformer I'll bet that one of the wires is solder to the frame. The other wire goes the speaker plug.     
Mike sez to try either 1 and 2 or 2 and 3 to connect to the speaker. Try both and see which sounds the best.

I was down in the basement in my dad's
