Just so I'm clear, it looks like the two wires that should test to 500 ohms resistance are for the two 71a tubes, located on the bottom two pins, and their order isn't important?

Is the order important for the two field coil wires (top two) coming off the speaker? It looks like these should show 3100 ohms resistance, but if the order is important how do I determine which wire should pin to D, for example?

I may just be overthinking this but sometimes I'm a knucklehead and have learned to be risk averse!
