I'll bet it's bad/dirty bandswitch contacts or conductive crud between contacts on the switch wafers decks maybe. Pin 4 of the 7F8 happens to pass thru two bandswitch contact sections when in the FM position, looking at the schematic. Could also be a bad/open/shorted FM osc coil on the same line there? If the FM osc is not running - no stations.
