I have actually run a wire through all of the 50 odd griplets that act as vias... I re-soldered every joint in the IF amp area, and there is still basically no signal coming out of pin 5, (if there is, than it's like .005v pp) If I bang and bop the set, or rap on the board, it seems pretty consistent in it's current state. When I turn the agc control (r150) pin 3 actually goes from 5.27v to 5.44v and seems very consistent, just 5 volts high...
