[Hallicrafters] HT-37 tuning dial

[Waldo Magnuson]

Everything is working fine and I've gotten the operational issues 
solved on my HT-37.
But one problem remains:  The tuning dial rubs on the red index wire at 
the top.  It appears that the phenolic tuning dial has, over time, 
developed a curvature (dished out actually) so that the clearance at 
the top is inadequate.  Has  anyone run into this problem and/or have a 
suggested cure?  Thanks.  Skip Magnuson
