Tried reversal of 1 and 3.. no reception at all.  with it hooked up by the drawing I receive 770 kc on 900 kc dial and others all up the dial but never below.  Note this is a 470 kc IF radio and the coil is spec at 455KC IF.  No adjustments on the coil makes a difference.  I can slightly shift the frequency by adjusting 3B ..
