There is a little 4 pin socket on top of the RF front end chassis, between the AM antenna terminal strip and the 6BA6 IF tube. The schematic shows the pin connections for the mating plug of the in cabinet FM dipole.

ok thanks hooked up antenna FM completely dead no noise or signals. AM works fine.

So either doing something wrong? or FM is bad.. Not sure what to check next.
