Broke it off aye. Well if it was from tightening it this may be the problem. As you tighten it you are increasing the capacitance of the trimmer. This lowers the oscillator frequency which in turn lowers the signal shown on dial. If it is still flatten down or the celluloid insulator is damaged this could cause the oscillator not to tune up to the top of the band.
Wouldn't hurt to bake the coil. Needs to been a fairly low heat like 150-175deg.

I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
