< The compensators 10&4 do not show any movement on the meter when trying to align the Broadcast band. 

You can check the rf coils by:
#1 measuring the resistance from chassis ground to red and then the black ant terminals. Both should show a low resistance. Jumper must be in place as shown on diagram.
#2 Measure the resistance from the junction of #'s 6 and 7 to the ant section stator of the tuning cap.
These steps checks the ant coil.  
#3 Measure the resistance from pin 3 of the 6K7 to the ungrounded side of #15.
#4 Measure the resistance from #7 marked B2 on the diagram to the stator of the rf amp section of the tuning cap.
These steps check the rf coil.
Rotate the band switch to measure the coil on other bands. All coil should be under 25ohms or so.

Could have a bad ant or rf amp coil. I remember Ron mentioning something about the 37-650 having a problematic band switch due to arcing and burning contacts.
