Typically all that means is the crystal needs to have its
trimmer capacitor adjusted back into range. I have no direct knowledge
of the TBolt's oscillator, but it might be as simple as removing
a screw, and adjusting the trimmer... Or, in some cases you have
to remove a solder blob from the metal can, and access the trimmer.
I would sure hate to toss away all that hard earned aged xtal for
a new one at this point.
