The alignment went OK save for one band: the 9.5 to 12 mc band. The tracking is off and while I can move the 12 mc signal lower on the scale, I cannot move it any higher than 11.6 on the scale - that is where the adjustment screw tightens up completely. The other bands all turned out fine.

Ron;
  It may be worth checking the molded micas associated with that band, particularly if they are in the oscillator tank circuit. Who knows, maybe one of them is slightly leaky, or increased in value and makes the oscillator run a little off?
