Would like to align an NC-121 receiver.  I've done one
alignment before and made out pretty well considering

to where to connect the signal generator and VTVM were
 very specific and easy to follow.  In the case of the
NC-121 the instructions for IF alignment include
connecting the high side of the generator directly to
the mixer section of the tuning gang."  Does this mean
the  stator, the rotor or something other?
An inspection of the schematic to see how the mixer
section of the tuning capacitor is connected in the
circuit should answer your question.  However, the
rotor is the most likely.
