The alignment marks still line up; there is a greater range of rotation built into the condenser than the dial mechanism has.  That was what threw me off, I thought the condenser stops are what limited rotation; and when both dial ends lined up, I figured the condenser was aligned.
I bought the repro dial from Radio Daze probably 5 years ago, when I first acquired the 38-690.  It is of a much darker material than the original, and doesn’t illuminate well (especially the magnetic tuning flood lights; you can barely see the preset station tabs).  Been thinking about either A) paint the bulb reflectors white or silver, or B) get some greater lumen warm white LEDs.
I still have the original dial, which I could glue back together if I can find another for some small missing pieces along the outer edge.
Now to construct a better aerial.....
