To answer your question on the dim bulb test with tubes out, yes, the bulb should not show any appreciable glow. The power transformer is under no load. You passed that test and that was actually a "safe" one to try (all tubes out).
As for your question on speakers, the large one is a full range speaker and the only "active" speaker in the radio. Notice the three small ones have no wires going to them. These are referred to as acoustic clarifiers and provide dampening of cabinet vibrations. It is some type of acoustic magic that Philco came up with.
