If my trimmers are OK, I guess I should forego tempting fate by doing an RF alignment, right? Sensitivity is pretty good right now.

The trimmer problem has been discussed extensively with respect to the RBS receiver which is the same.  If I remember right, a press-fit bushing cracks and the shaft gets pushed endwise by the wiper spring.  I shifted the rotor and soldered the bushing.

RBM suffers from the same issue with the trimmer variables' rotor shifting endwise and shorting out the capacitor.
