By pilot light I mean the bulb that lights when I turn it on.

Here is a link to a website that will provide you with the pinouts of every tube in your radio. Here I have specifically linked the 35B5, but you can use this site for all the others as well. And no, the heaters do not go straight to ground, they are in a series string, as Old Coot said they are like modern Christmas lights, one burns out and they all go out (old time Christmas lights were in parallel)
