What schematic are you using? The Philco factory service info gives this information, as does the schematic in Rider's. The bulbs are shown just to the left of the AC plug on the schematic. The bulb in question is the one on far right of the group of five - notice how its lead goes to terminal B9 on the band switch.
Either the switch isn't making good contact, or else the contact inside the lamp socket isn't making good contact with the end of the bulb itself. Also, the other side of the bulb is grounded; make sure it is so in your set.
Check to see if you have 6.3 volts AC between the contact in the lamp socket and ground with the band switch in the "pushbutton" position.
