I have a 305U with the later round IF cans.  Every picture I am seeing has a cutout at each side of the dial for two dial lamps.  Mine has one cutout and one dial lamp.  The reason I am going into detail is the bottom half of the tall dropping resisot is open.  The schematic shows this section to be 200 ohms for 2 dial lamps.  Do I have an earlier version and if so, what will the value of the bottom half of this resistor be?  Also, the top half measures 900 ohms. This would seem to be more in keeping with one bulb.

 

Best regards,
